I suspect the "Ms." part is not representative of Ms. magazine, as feminists had other priorities at the time that did not involve a nude man with a shoulder length mullet. Which by the way, he wins! Though each of the other guys has lovely qualities.
I must ask, however, what is the deal with the cock rings on soft cocks? Maybe they are like the way the grocery store marks individual carrots with a wraparound "Organic" sticker. Except in this case, the sticker reads "penis" or whatever the word for that was in 1976.
Some googling shows that "Ms. All-Bare" was a (suprise!) naked lady pageant. So this shot must be from the titter-worthy male section. I expect this aired on network TV right between Starsky and Hutch and Marcus Welby. Um, or never.
