The cards in your link are not certified by Upper Deck. Both are regular insert cards that were signed by Hull after the release of the product. Beckett only authenticated that the signature was real. It does not say on the label that these are Heroes Autographs. That is why there is no serial number. They are NOT the pack-released AU cards.
NO PWE's EVER!!! PLZ PM me 1st before sending any offer. ONLY selling cards as of March 2024. No trades or purchases right now.
