Sub-Mariner #27

In "When Wakes the Kraken!", Namor faces off against the fearsome Commander Kraken, a ruthless pirate with a hook-hand and a giant squid submarine, as he terrorizes the surface world by targeting radium shipments. With Dorma and Diane Arliss taken hostage, Namor must outwit the pirate and expose his true, monstrous threat—the ancient Kraken lurking in the deep. Written by Roy Thomas and illustrated by Sal Buscema, with inks by Joe Gaudioso and letters by Sam Rosen, this 1970 Marvel classic features cover art by Sal Buscema and Mike Esposito.
