2007 Marvel Comic USPS Super Hero Stamp and 8 similar items

About the item: This trifold pamphlet/order form was released in 2007 by USPS. It is unique in that it has the actual Spider-man First Day of Issue Cancellation stamped onto it. Generally, such cancellations are used only for the special envelopes the stamps they feature but this is a rare instance of a promotional item with the cancellation. This special cancellation debuted at the 2007 San Diego ComiCon, where USPS offered to cancel the stamps purchased by attending fans. There was quite the fanfare surrounding the stamp release at the show. Both the front and reverse of the form (which has been unfolded to be scanned) are shown in the images. ~Certificate of Authenticity/Provenance: Excepting pack-pulled autograph trading cards, CGC Signature Series, signed Sideshow prints, and like collectibles, all autographed items Vault Collectibles sells were personally witnessed, by myself, being signed by the writer, artist, or celebrity in question. No third party is involved. Further, art sketches - and most published original art I sell - were obtained directly from the artist themselves.
