The Incredible Hulk #182

In "Between Hammer and Anvil!", the Hulk, fresh from a grueling battle with Wolverine and captured by Canadian commandos, breaks free and crosses paths with the eccentric Crackajack Jackson. As the two form an unlikely bond, the Hulk joins Jackson on a journey to visit his son in prison—only to find that the son, Johnny Anvil, is now a hardened convict with a dangerous past. Meanwhile, the escaped duo of Hammer and Anvil, transformed by an alien force, return to exact revenge. Written by Len Wein and illustrated by Herb Trimpe, with colors by Glynis Wein and letters by John Costanza, this 1974 Marvel classic features a cover by Herb Trimpe that captures the tension of a fractured reunion.
