    Sub-Mariner #1 (1968): Namor's Silver Age solo series

    Sub-Mariner #1 (May 1968), by Roy Thomas and John Buscema, launched Namor's first solo title of the Silver Age after his feature in Tales to Astonish ended. It is one of the 1968 Marvel expansion #1s — with Captain America #100, Iron Man #1, Silver Surfer #1 and Nick Fury #1 — and a solid Silver Age key with a Buscema origin retelling. Namor himself dates from Marvel Comics #1 (1939) by Bill Everett.
