OK, "World Premiere" is a bit overblown for a 63-year-old magazine cover. But this is the first time it's been on the internet. I've been looking all over the internet for this graphic and couldn't find anything that showed Gerald Ford's work as a male model in his younger days. So I wrote to the Gerald R. Ford Library, and Archives Technician Brooke L. Clement was kind enough to respond very promptly:
According to Carole Conover, in her book Cover Girls, President Ford also posed with Ms. Brown for a Cosmopolitan cover, issued in April 1942. I am attaching a photo of this cover (we do not have the cover at either the Gerald R. Ford Library or the Gerald R. Ford Museum). However, we at the Library cannot confirm or deny that it is President Ford in that cover.
Just between us, let's say that it is future President Ford in that cover illustration, OK? Many thanks to Brooke and the entire Gerald R. Ford Library for their help uncovering this artifact!
Oh by the way, you might enjoy this story from a couple of years ago as well.
