The artwork is by Geoff Campion (1916-1987). He's best known as a Western and WWII artist on Amalgamated Press/Fleetway titles of the 1950s and '60s, such as "Sun" and "Comet" (see posts) and "Valiant". But he drew occasional historical strips as well. For Thriller Comics/Picture Library he drew "Robin Hood" (story one) TCL No10 (Mar 1952) and "Quo Vadis" TCL No19 (Aug 1952), based on the MGM film. He also produced ten title pages for TPL "Robin Hood" issues (1957-59) and a full-colour serial, "Dick Turpin and the House of Secrets", for "Sun" (1958). It's surprising that anyone could find his work 'old-fashioned', even today - at the time, his clean vigorous drawing was the epitome of picture-strip modernity. His mastery of action scenes led to him being overused, to the detriment of his work. (Lambiek Comiclopedia * Ashford & Holland: "The Thriller Libraries" London 2010)
