Tales To Astonish #35 (Sept 1962)

Ant-Man is a rubbish superhero. He has the strength of A MAN, and the size of AN ANT. He invents the marginally more useful power of talking to ants, so he can get their help to defeat some Russian spies. Weak. At least there's a nice story about a flower that thinks it's a man at the back.

Tales To Astonish #27 (Jan 1962)

Henry Pym is a shitty scientist. Astonishingly, this gets him into trouble.
