Valiant and Knockout #23 February 1963

"The Fang [Part 1]" kicks off in Valiant and Knockout #23 (February 1963), a 6d comic from IPC, as Nick Shadow escapes prison under cover of a fake conviction—only to find himself drawn into a deadly mission to shield British scientists from a foreign assassination attempt. With bold artwork by Tom Kerr, the story unfolds with tense intrigue, and the cover by Geoff Campion captures the shadowy danger ahead.
