The Frasier Crane Painting

After watching Frasier for years on television for years (it’s on almost as much as Friends and Come Dine With Me) I kept noticing the abstract painting on the wall in his apartment. I’ve always liked it and decided to do a copy for my bedroom wall. I went on the Frasier website and found “what is that painting in Frasier’s apartment?” is one of the most common questions. It was painted in the 1930s by Jack Otterson and is now owned by an art company in Los Angeles. It’s become so popular they’re started producing prints of it.

Anyway, here it is. Apparently someone told me that when you copy of painting (not a fake but a copy) you’re supposed to make one obvious but subtle error just to show it’s a copy. Can you spot it?
