Fantagraphics Bookstore in Seattle! (photo by Janice Headley)
Coming soon to a store near you...
PS: In anticipation of your questions: the book is published by Abrams, not Fantagraphics, but Fantagraphics sometimes sells graphic novels by other publishers in their store.
PPS: Frank Young and David Lasky will be doing a book signing at said store with Noah Van Sciver on November 2!
