Jack Harte was another popular beefcake model in the 1960's.
The two images of Jack in the dark posing pouch were taken by Al McDuffie, who also photographed male models under the names, ACME and California Models.
The other two images are similar enough that he might have taken these, too, though I'm not certain.
I especially like the photograph of Jack in his jeans not only because of his fantastic smile but because his pants provide a little perspective on what a massive bodybuilder he was.
