They didn't say how long his painting stayed up before it was noticed.
If it was more than a week, I say don't fire the dude, give them a grant.
Honestly I'd admire his bravado and leave it up. Makes for an interesting story for the museum.
Banksy snuck an artwork into the British Museum. They put it up in a real exhibition years later.
I was going to reply to another comment that if Bansky did this, they'd all be jacking each other off to get a look. Turns out that already happened.
Yeah, but it also meant he got to be on display in the gallery without the clout chasing and schmoozing normally required, and I'm sure they feel that has to be punished.
Tom Green did this decades ago.
Banksy too.
Binder paper. Tight.
