[Linked] Campbell's promo comic Spidey/X-Men

BBDO /Campbell’s Diversity: Ultimate Spider-Man / Ultimate X-Men

I just sold a copy on eBay and noticed there’s no price linked to CovrPrice. Let me know if there is additional info you need!

I looked it up on Covrprice and even though they list the book they have no value listed for it on their site

Linked but like @timeman1 said, there is no value for it yet
