By Stan Lee, Jack Kirby, Don Heck. Before he became one of the Avengers, Dr. Henry Pym was a man with big ideas. His contemporaries in the field of chemistry laughed when he first suggested his theories of spatial relations. They jeered at his beliefs that objects could be shrunk and later enlarged to their original size. They made Dr. Henry Pym feel very small indeed. And so, without their support and the proper funding, Henry created a serum based on this theories and then proceeded to experiment on himself. And he shrunk to the size of an ant. That is where the nightmare beagn, as well as the beginings of a hero. Collected here for the first time are the classic adventures of Dr. Henry Pym, the astonishing Ant-Man, and his stories as told in Tales to Astonish #27 and #35-69. SC BW 528pg.
