Marvel Universe Series II cello pack

This is the Marvel Universe Series II "cello pack". These cards were distributed to retailers in sealed cellophane packs to promote the upcoming series. They have the small "1991" text in the front corner like the variants of this same set as well as subtle differences on the back. Credit to abs-cards.net for the differences listed in the caption.
