Speaking of Chicago, one of the city's — nay, the world's — greatest shops for comics and zines, Quimby's Bookstore, is celebrating their 20th anniversary with this limited-edition 5-color silkscreen print of Chris Ware's blueprint for the store's sign, printed by the estimable Jay Ryan's Bird Machine press. Unsigned copies are available now and Quimby's promises that signed copies will be available at some point in the future.
