Don Fuller is one of my all-time favorite beefcake models. He was photographed by many of the top physique photographers of the 1950's, and appears in both The Male Figure and Physique Pictorial. I think he looks like he should have been a matinee idol.
Here are four outstanding photographs of Frank Hillgardner. I do not know who took these photographs nor who the other two models are. I will update this post once someone has identified them.
Here are four photographs of Doug Felton, of whom I know nothing. If someone told me he was their squeaky clean neighbor in the early 1960's, I would believe them. He seems delighted in these outdoors photographs.
