Linda,
Oops! I was off by a factor of 2 on the odds of guessing both correctly. It's really 1/153. The odds of getting one correct are 1/9. So I beat the odds, but I admit that I was purely guessing.
I considered #11, but reckoned that my wife was the only person in the universe who could get away with leaving that stuff on the dresser long enough for somebody to draw/paint it. My third choice would have been #2, the roses, followed by any of the still lives.
But I'm heartbroken that you spilled the beans right away. I was looking forward to lots of participants taking a shot at determining the souces, as a beautiful little experiment on the topic of this thread. Granted that we're looking at digitizations of photos or scans of these works, but we could have quantified how easy or difficult it is to identify source material in the finished work under these circumstances. It was fun anyway!
