AMAZING SPIDER-MAN (1963) #340, [VF/NM (9.0)]

Due to concerns about his dear aunt's health, Peter debates whether or not it's time to give up being Spider-Man. And fortuitously he bumps into a doctor on the street that might be able to take away his powers! But has Spidey checked the references on this mysterious Doctor Turner? That might be a good idea first! In the meantime though, the wondrous wall-crawler has a rendezvous with the Femme Fatales at Kennedy Airport! And these ladies play rough! First appearances of Knockout and Mindblast.
