I drew this back in 2005 (hence the 2005 Batman) for The Believer, then it got ganked and spread around the internet with some dumb text added to the bottom. 

Available in three sizes: 9" x 12" (not limited), 11" x 14" (limited edition of 100), and 17" x 22" (limited edition of 50). Hand-signed and hand-numbered (if appropriate) in pencil on lightly-textured Velvet Fine Art paper.
