You are considering a CGC 6.0 copy of Amazing Spider-Man 37, featuring the first appearance of Spider-Man's greatest enemy, Norman Osborne, the Green Goblin!
It also features the first appearance of Mendel Stromm, the Robot-Master! Story by the immortal Stan Lee and art by the peerless Steve Ditko!
I combine shipping. Since this is a book with condition certified by a 3rd party, no returns are accepted.
Thanks for looking!
