"Eric the Viking", a continuing serial featuring its eponymous Viking hero, and set in the Dark Ages, was another reprint from "Lion", where it had run under the title "Karl the Viking", as a set of 13 stories, from 29 October 1960 until 29 September 1964, written by Ken Bulmer.The change of name to Eric probably reflects on the continuing fame (during the 1960s) of a real-life Viking leader in Dark Age Britain, Eric Bloodaxe, who history records was King in Viking York in the 10th Century.
