norville’s framed Mona Lisa, a stenciled portrait in a gold bamboo frame, hanging on a white cinder-block wall next to a red brick building

Thank you for
stealing the
Mona Lisa

Collaboration

You finished it.

The piece you took off the wall was only half done when I hung it. I painted the face, framed it and put it on a hook. Taking it was the other half, and that makes you a collaborator. The work is credited to both of us.

We’ll probably never meet, so your name on the label stays blank, which seems right for a thief. Hang it up or give it away. It’s yours now.

The Concept

norville’s Mona Lisa: a stenciled portrait of a woman in glasses with her hair pinned back, MONA above her and LISA below, in a gold bamboo-style frame

Ever notice that whenever there’s a heist to steal a painting, it’s always the Mona Lisa? The idea was to bring the rush you get from stealing a priceless artwork to the people.

I make Mona Lisas and hang them in public but secluded spots. Each one just sits on a hook on the wall with nothing protecting it, until someone steals it and leaves a shadow where it hung. And voilà, you stole the Mona Lisa!

Once it’s stolen, the piece is complete.

Mona Lisa as an idea

The Mona Lisa is not just a painting. It’s an idea. It started in August 1911, when someone carried it out of the Louvre.

Until then it was a respected Leonardo in the Salon Carré. Critics liked it. Most visitors walked right past. Vincenzo Peruggia, a handyman who had helped put in the museum’s protective glass, spent a Sunday night in a storeroom, lifted the panel off its hooks the next morning, slipped it under his smock and walked out. Nobody noticed for most of the day. The guards figured it was off being photographed.

The museum closed for a week. When it reopened, people lined up to look at four iron hooks. Kafka and Max Brod were in Paris that fall and went to see the gap. The face was on front pages for weeks; Apollinaire spent a few days in jail on suspicion, and Picasso was brought in for questioning. For two years the painting was only reproductions and rumor, and somewhere in there it became the most recognized picture in the world. Peruggia had it the whole time, in a trunk in his room in Paris. In December 1913 he took it to Florence and offered it to an art dealer, Alfredo Geri, who called the police. The painting came home with a story attached, and that story is a large part of why people still line up to see it.

In pop art

Once she was the most famous face in the world, artists started borrowing her.

In books and movies

Dan Brown’s The Da Vinci Code turned her into a puzzle. The book opens with a murder in the Louvre, and one of the first clues is written on the glass in front of the Mona Lisa. It sold tens of millions of copies, and the movie followed in 2006.

Movies keep coming back to her too, usually as the thing in the heist.

Marcel Duchamp and the Creative Act

In April 1957, Duchamp gave a short talk in Houston called “The Creative Act.” His argument was that an artist can only take a work partway. You start with an intention, you end up with an object, and there’s always a gap between the two. The viewer closes it by looking, interpreting and deciding what the thing is worth. In his words, the creative act “is not performed by the artist alone.”

He’d been working that way for a long time. In 1919 he drew a mustache and goatee on a postcard of the Mona Lisa, lettered L.H.O.O.Q. underneath, and left the joke for the viewer to find by reading it out loud. She’s been the picture people reach for ever since when they want to argue about copies and who owns an icon.

This project takes his idea one step further. A viewer who looks and interprets still walks away and leaves the piece on the wall. Here the viewer has to become a collaborator. You decided to lift it off the hook and carry it out, and that’s what completed it.

Theft

Theft is where you come in.

A copy on a wall is one of millions. Once someone wants it badly enough to take it, it gets a history of its own: it hung here, someone took it, nobody knows where it went. That’s 1911 again on a much smaller scale.

Banksy got to a version of this by accident. People started cutting his pieces out of walls, and the cut-out pieces got more attention and sold for more than they would have where he left them. The shredder came later, and that one was on purpose.

The theft is the part I leave to you. I provide the face, and somebody else has to commit to it. You made a choice nobody asked you to make, which takes more than looking does. Peruggia said he did it for Italy. You have your own reason, and it’s part of the piece now, even if I never hear it.

The New Monas

Why it’s not a copy of Leo’s version.

Leonardo painted one woman, Lisa Gherardini, and for five hundred years hers is the face everyone copies. Duchamp gave her a mustache and Banksy handed her a rocket launcher, and her face stayed the same.

Mine keep the name and the gold frame and swap out the woman. Each one is somebody different and gets a number. The one you have is one of them.

Each Mona is made once. After it’s sprayed, the stencil gets destroyed, so there will never be another one like yours.

Yours has a certificate of authenticity attached to the back. Keep it with the piece, and please don’t post it online.

L.H.O.O.Q.

Close-up of the bottom rail of a gold frame, with L.H.O.O.Q. hand-lettered in black marker under the stenciled word LISA
On the bottom rail of every frame, yours included.

The letters are a joke you only get by saying them out loud. Read them one at a time in French and you’re saying the letter names: elle, ache, o, o, cu. Say them fast and they run together into a sentence.

L
elle
el
Elle
H
ache
ahsh
a ch‑
O
o
oh
‑aud
O
o
oh
au
Q
cu
kew, lips rounded
cul.

Word by word:

elle
she
a
has
chaud
hot
au
at the, in the
cul
ass

Literally it’s “she has a hot ass,” and it’s slang for being turned on. Cul is the vulgar word, nearer to arse than to bottom.

So Duchamp put a mustache on the most respected woman in painting and captioned her with a dirty joke that stays hidden until somebody reads it aloud. The frames use the same trick. Now you know what yours says.

The empty nail

Each hangs from a single nail or hook and lifts off easily, so taking one is a quick decision.

Each one gets photographed in place, then again after it’s gone. How long it lasted gets written down. A Mona Lisa that lasts three months tells you something different than one that’s gone by lunch. The first one lasted a day. There’s a photo of the empty spot yours left behind, too.

FAQ

Did I just steal a painting?

Technically, you finished one. Taking it off the wall is part of the work, so it wasn’t complete until it left with you.

Am I in trouble?

Not in the least, thank you so much!! It was hung there to be taken, and you took it. That was the arrangement all along.

Is it really mine now?

It is. Hang it somewhere with decent light and keep the certificate with it. If you’d rather pass it on, give it to someone who’ll appreciate the backstory.

Why the Mona Lisa?

Every heist movie goes after her, and the art world has been arguing about copies of her since Duchamp drew the mustache in 1919. She came with a hundred years of context already attached.

Will there be another one like mine?

No. Each Mona is sprayed once and the stencil is destroyed, so yours is an edition of one.

Who is the woman in mine?

Somebody different every time, on purpose. The New Monas has the longer explanation, if you want it.

What does L.H.O.O.Q. on the frame mean?

It’s a nod to Duchamp. Read the letters out loud in French and you’ll get the joke, which is a little rude. The L.H.O.O.Q. section has the translation.

Where will the next one go?

Somewhere public and quiet, probably in Lake Oswego. I don’t announce locations ahead of time. It would take the fun out of finding one.

What happens to the spot where it hung?

It gets photographed with the empty nail still in the wall. The absence gets documented as carefully as the painting did.

Can I post about it?

Please do. With stolen art, knowing where a piece ended up is half the story. Just keep the certificate out of the photo.

About

norville makes Art in Lake Oswego, Oregon. But not in the lake.

He is in search of a creative life. Failing at everything else, he’s driven to street art. Most of it starts from the same habit: to understand a thing, he makes it again. He separates what a work is trying to do from the object itself, then rebuilds the object until the intent shows.
