George Rozen, best known for his iconic covers for The Shadow Magazine, spent much of the 1940s painting dozens of covers for Thrilling Publications, including westerns, crime & war magazine in addition to, of course, The Shadow. (clue #1).
One other pulp artist with a (not surprisingly) similar style to George Rozen was his older brother, Jerome, who preceded him on The Shadow, but after World War II Jerome Rozen left the pulps for the far more lucrative world of advertising illustration. (Clue #2).
Though the cover of this issue of Masked Rider Western is uncredited, and no online source seems to provide credit, Rozen painted a good number of covers for the magazine as well as other Thrilling branded westerns throughout the late forties. (Clue #3).
While comparing the western elements of this issue’s cover is useful (guns, horses, landscape), funnily enough, it’s the facial features that really set off the alarm bells. George Rozen is best known for his work on The Shadow, a character with a heavily obscured face, but terrific detail was put into what you could see, primarily eyes, nose & cheek bones. And while The Masked Rider lacks the alpha schnoz of a certain Lamont Cranston, the focus & detail of the facial work, for me, puts this one over the edge. (Clue #4).
So there you go, the February, 1950 issue of Masked Rider Western magazine (Canadian Edition).
