  • 1st full appearance of Norman Osborn, not in Green Goblin costume, identified by name
  • 1st appearance of Mendel Stromm, later becomes Gaunt and then Robot Master
  • 📉 Spider-Man movies are going to be around for awhile and we've already heard Osborn is going to be introduced. Although this isn't the FIRST appearance of Osborn as Green Goblin, it is Osborn as a businessman akin to Lex Luthor and therefore gets its own Key Issue designation
  • By comparison, this issue sells for about 1/3 of the price that Kingpin's first appearance sells for in The Amazing Spider-Man #50
