TO SEE OUR UPCOMING SIGNINGS: TWINCITIESCOMICS. Jeremy Renner Signed Avengers Endgame Mini-Poster #1 (11x17). Signed by Jeremy Renner at our private signing with him. Independently authenticated through Beckett with witnessed certification. This type of witnessed authentication sticker is only placed on items that a Beckett representative witnessed being signed and is stickered immediately.
(Think of it as a notary public where the authenticator is confirming they witnessed the actual item being signed by that actor). Certification numbers are unique on each individual item. While extremely rare, an item could sell on one platform and also sell on another platform before inventory updates.
