Public Domain Art from Artvee

If you're a regular gallery or museum goer, you may want to check out Artvee, a site for viewing and downloading public-domain art. You can browse by category (for example, landscapes), movement, culture, or artist, or view curated collections. The collection of NASA Visions of the Future posters is one that I especially liked.

Given that all the art is in the public domain, you won't find much by current or 20th-century artists, but there's certainly enough here to keep you browsing for hours.
