…who painted this picture?
It’s a portrait of Barney, the Scottish Terrier who used to be First Dog back when George W. Bush was president, and who died Friday at the age of 12 of lymphoma.
Note that “43″ in the lower right hand corner, where a painter’s signature might be. That’s a clue.
[NOTE: I don't know if it's also true of painting them, but black dogs are notoriously difficult to photograph well.]
