I am searching for a copy of a picture that my folks owned when I was a kid. I have only a very small snippet of the picture, which I posted under "Questions', but no one seems to know the painting or the artist. Is there a site that I can go to that will have an extensive "catalog" of pictures that I can browse through to try and find it? I'm not opposed to buying a copy, but I need to know the title and artist first. I thought the title was "The Argument" or "The Debate" but I've had no joy with those titles. Allposters.com doesn't seem to have it. Am I asking the wrong questions? I know very little about the visual arts, but I would dearly love some help! Thanks!
