AKA aka Joe Mario; seems to be just the one photo session that I can ascertain, and the pics show up in 2 magazines – Magazine #1 from 1978; he's the cover model and there's a 16 page spread of him, solo – Joe Mario. Also appears in Champs #1, published in 1981, same set of images, just 7 pages, and he's "Mitch." I wouldn't be surprised if he made it into a Honcho or Mandate between '78 and '82, but I would be surprised if we find an image not included in these 2 magazines already.

Once upon a time, I had this magazine, and believe me, it was well-used. Picture it, 1978, any gay bar in America. This was the archetype we—or at least I—ascribed to and simultaneously got my motor running. To this day, that remains true, and while I love, love, love beards, I am also so happy to see 'staches making a comeback.
