The persona of the American male in the period between the two world wars was characterized by physical strength, emotional detachment, aggressive behavior, and an amoral worldview. This ideal of a hard-boiled masculinity can be seen in the pages and, even more vividly, on the covers of magazines such as Black Mask, which shifted from Victorian-influenced depictions of men in top hats and mustaches in the early 1920s to the portrayal of much more overtly violent and muscular men.
