Detective Comics #27 comic book from DC Comics
The first appearance of Batman, the second most popular character in comic history.  I still like his original costume best, with the cape that really looks like bat wings.  I am not sure if this is a scan of the original or a reprint (by the condition, I am guessing reprint), but it was sent to me.  Thanks for the nice scan, Glenn!
