Art Frahm (1907-1981)
Art Frahm, a Chicago area artist whose commercial art ranged from magazine cover illustration to zany "hobo" calendar paintings, excelled in (and perhaps created) the "ladies in distress" series for the Joseph C. Hoover & Sons calendar company, in which a lovely girl is literally caught with her panties down, her lacy undies slipping to her ankles while she's in the process of bowling, walking the dog or changing a tire. Frahm was commercially successful. His falling-panties paintings are still considered too camp to be art, and too juvenile to be erotica However this genre (which Frahm seems to have created) was in demand in the 1950s, and was later imitated by some other pin-up artists.
