When I was in San Francisco a couple of months ago I got a chance to attend a big Obama event/party and met some cool artists doing Obama posters, stickers and shirts under the name of january20th2009. They make their artwork free to download via their flickr page. With their blessing I have worked on turning one of their designs [Forward] into a 1.25 inch button design which is available now on the templates page. I love the simplicity of this message: Forward!
