A couple weeks ago, David Marc Fisher's Blog About Town pointed out some intriguing affinities between Edvard Munch and Edward Hopper with some clever examples.
Mine are not quite as striking (or even accurate), though I had fun searching. Shown here, left to right, are Munch's "The Day After" and Hopper's "Summer Interior." You might also compare Munch's "Morning" and Hopper's "Eleven A.M." here.
Incidentally, Norwegian police recovered Munch's "The Scream" and "Madonna," which were stolen from the Munch Museum in Oslo two years ago. The Washington Post has a good write-up and BBC News has a picture of the theft.
