The Incredible Hulk 1968 #121 - reader copy - $14.00

Hulk is leaping over Florida when he is accidentally struck by a missile causing him to crash land in the swamp. Finding a cabin, Hulk destroys some barrels of radioactive waste which creates a muck monster soon to be known as the Glob. The army is in the marsh hunting the Hulk when the Glob captures Betty, thinking she is the woman he loved back in the days when he was a human. The Hulk and the Glob battle but the muck monster ends up giving his life in helping the Hulk save Betty from anti-radioactive goop that Ross has poured into the swamp in order to kill both the Glob and the Hulk.
