All art is in the public domain and free to use for posters, flyers, tard signs or however you see fit. All are high-res (300dpi) 11x17 originals and should print fine at twice that size with not too much degregation. All are in the .png image format.

Suggestions for varients, or other poster ideas, are welcome. Or if you need something other than a .png, post as a comment here or with the hashtag #ArtForChange on Twitter.
