President-to-be Gerald Ford worked as a male model in his late 20's and was featured on the cover of Cosmopolitan in April of 1942 in his Navy Uniform. Here is a color image of that cover of Ford and his girlfriend at the time, which was previously available only in black and white:
Ford was not credited for posing for the illustration, but as luck would have it he met his future wife, Elizabeth Bloomer, while working as a model.
Bonus photo: Gerald Ford campaigning on an elephant in Michigan shortly after the above cover shoot, in 1950.
