Okay, 1947 is a bit outside the Golden Age, but how's this for a 1940s pin up? The sketch is a preliminary drawing for the Steve Canyon comic strip, which was created by artist/writer Milton Caniff. Caniff (1907-1988), whose nickname was "The Rembrandt of the Comic Strip" because of his influential inking style, began the Steve Canyon comic strip in 1947 because he wanted complete ownership of the property. His previous creation, Terry and the Pirates, was a popular comic through the 1930s and made Caniff a household name. Caniff wrote and drew Steve Canyon for forty-one years. The strip ended with his death in 1988. However, the comics have been reprinted in multiple volumes and are widely available.
The illustration was based on Gary Cooper, whose long, lean fame served as the inspiration to the thoughtful, patriotic man of action, Steve Canyon.
Another element of the comic was Caniff's various female villains. Glamorous, dangerous, and attractive, a "Caniff Woman" like Copper Calhoun was a wondrous creation, indeed.
