Wold like to buy a framed poster, ideas on artist names?

Framed Art Posters. A friend recieved a beautiful framed art poster that she now keeps abover her fireplace. She says there are sites that sell art posters, framed. I think it's a great idea, and wold like to buy a framed poster myself. Bing the art buff that I am, I would need a great variety to choose from. I like some of the less well known names in art. any ideas.

Art is such a personal thing that I would go find a poster store in the mall first before going on someone's recommendation of what is "good art". There usually is a store in any mall that sells art and posters.
