This rare postcard, originally created to be included with the 1984 George Pérez 15-card Justice League of America set, was purposefully left out. Batman, having left the JLA to form the Outsiders, was no longer a team member and so DC opted to give out the card as a premium to convention attendees. The card, which measures approximately 4 by 6 inches, is in excellent condition with only some minor corner wear as well as some discoloration spots on its back side (see scans) and will be shipped with the utmost care. Please note- the signature is real. It is the actual, hand-signed signature of Pérez. It is not a pre-printed image on the postcard.  Includes Vault Collectibles COA. 

A Word About 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.
