Coming in paperback and available August-ish, quite possibly at a bookstore near you:
Catalogs have been shipped and an Amazon page created, so I can talk about it now. Paperback. $14.95. Exactly the same size and content as the hardcover, including the cool pulpy comic book paper. A new cover designed by me, Abrams graphic artist Sara Edward-Corbett and Art Director Chad Beckerman, with valued input from Editor Charlie Kochman.
Funnily enough, despite producing all the art and working on the cover with Abrams for weeks, I just realized now that the only version I have of the final composition is this relatively low-res image from Amazon. The sticker at top left is the American Astronautical Society's Eugene M. Emme Astronautical Literature Award; the quote at top is from The Village Voice: "A hopelessly optimistic moon-age daydream," which I've always chosen to take as a compliment.
Much more later!
