Superman #73

This November–December 1951 issue promises a fun wrinkle on Superman's usual heroics, as the cover declares he's about to meet "Hank Garvin, Man of Steel!" — and the scene makes the premise immediately clear. A confident, ordinary-looking man in street clothes stands completely unfazed as a massive industrial machine fires debris straight at him, while Superman flies overhead, pleasantly surprised and noting there's no need to intervene. Win Mortimer's cover art captures that delightful moment of Superman meeting someone who might just be his equal, packed into a generous 52 big pages for a dime.
