The so called “potty mouth” All-Star Batman and Robin #10 fiasco you may have heard about is still creating quite the story in after market comic book sales. A copy of the issue on EBAY has an asking price of $500 (although others are offered much cheaper). For those that missed this publishing event, some bad file management caused the black bars used to cover-up a character’s foul mouth to not work so well. DC Comics tried to recall the books, but at least some retailers saw a potenital profit in an instantly “rare” comic.
