Tales to Astonish #27 (Marvel, 1962) is the first appearance of Henry Pym in "The Man in the Ant Hill!" — the scientist who would become Ant-Man and a founding Avenger. Published the same year as Hulk #1 and Thor's debut, it is one of the foundational first appearances of the early Marvel Universe, and it predates Pym's costumed Ant-Man identity, making it the true origin point of the character.
