I’m a big old fan of art-for-the-people site 20×200. Their prints are super well-priced, and they make the browsing process both fun and unintimidating. You can search by color, theme, and price range—something that would surely be viewed as pedestrian at similar venues. And every print is available in a nice selection of sizes. Right now I’m liking them especially much, as they are donating proceeds from each piece in their New York Collection toCitymeals on Wheels.
