Further complicating the "Are these really Ant-Man's stories?" question is the fact that, in Tales to Astonish #49, Ant-Man changed his suit, broadened his power set to include size increase as well as size decrease, and became Giant-Man. And although he was always Giant-Man on the cover of the comic, Hank often shrank down to Ant-Man size in the pages of his adventures, meaning that effectively categorizing these stories is just slightly bothersome.
