The Man In The Crime Master Mask (ASM #26)

Summary: Spidey fights not ONE but TWO villains with secret identities: The Green Goblin and also -- THE CRIME MASTER! It’s yet another guy who’s plan is to unite all the crime syndicates in NYC! Will the fact that Spidey-Man has to use a cheap rented costume slow him down! Hint: yes! Kevin and Will like this issue as they realize that they had underestimated this particular era of the Ditko-Lee partnership.
