Incredible Hulk #181

The first appearance of Wolverine! And he throws down in one of Marvel’s greatest battles with the Incredible Hulk! The clawed Wolverine leaps out from the top of a rocky hill landing between the Hulk and the Wendigo. Scurrying onto the Hulk’s back, he begins swiping at him with his diamond-hard Adamantium claws, but even they cannot pierce the Hulk’s skin. Realizing that the Wendigo may prove to be an easier target, Wolverine springs over the Hulk’s head and launches himself at the Wendigo. His suspicions prove correct, and his claws rake into the woodland creature’s hide.
