About the item: Released and stamped with the special First Day Issue cancellation at the 2006 San Diego Comic Con itself (where the stamp also debuted), this official USPS stamp features Aquaman with artwork by Curt Swan. In nm/mint condition, it will be shipped with the utmost care. Please note- the signature is real. It is the actual, hand-signed signature of Keith Giffen, the writer of the comic depicted. It is not a pre-printed image on the FDI. ~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. For buyers desiring this guarantee in written form, this statement guarantees that the above referenced item is as stated in the listing description. A screen capture of the completed auction page, which includes this statement of provenance, may be saved by the buyer as a digital file or print off in hardcopy form. As this serves as written proof of said guarantee, no physical documentation will be included in the package when the item is mailed. J. Brian O?Bryant VaultCollectibles dba as empire.auctions
