Thanks for answering! If you have any pull, get them to collect DeMatties & Zeck's Captain America 275-283, please. Each issue is by Dematties & Zeck of Kraven's Last Hunt fame. It features the debut of Zemo, which I can't believe has never been reprinted. It also has a great storyline with Viper as the villain. Conway and Sal's Spidey has Tombstone, Oneil's Iron Man has Obadiah Stane, and Stern's first Avengers story arc with Buscema and Palmer on art features Nebula, who is tied to Thanos lure
