The listing, Batman 2006 Superhero stamp set, First Day of Issue MINT in plastic has ended.
Commemorative Batman First day of Issue stamp in the Superhero collection of 2006 is displayed wonderfully here with white matte. Mint condition, still in plastic. The top is a print of the stamp, which depicts the Batman #1 comic book cover. Below is a commemorative Super Heros envelop showing the entire collection and with the actual Batman stamp adhered in the top right corner. "San Diego, CA 92101 DC Comics First Day of Issue July 20, 2006" is printed below the stamp. Purchased from the San Diego Comic Con in 2006 by a friend, given to me 2 years ago.
