Want proof that art and charity can go hand in hand? Click over to The Working Proof, a new site that sells affordable, limited-edition prints that are paired with a charity of the artist's choice. Founded by printmakers Anna Corpron and Sean Auyeung, the online venture aims to showcase emerging artists and promote a variety of charities. Fifteen percent of the sale of each print goes to the designated cause, which means you can pick up Caitlin Keegan's funky, engraving-inspired print of a rooster and donate to Farm Sanctuary (all for $30 plus shipping). Avoid speedy sell-outs by checking in with The Working Proof on Tuesday afternoons, when a new print is released every week.
