Searching for 1968 Physique Pioneer Mike O'Donnell

I was asked to check if anyone knows the name of this model, who did nude physique portraits in the 1960s.  He appears under the stage name Mike O'Donnell.

Most of the models from that era were amateurs, whatever trick the photographer happened to invite home last night, or saw on the street and asked "Do you want to make a few bucks?"  Their careers began and ended in anonymity.

But Mike O'Donnell seems to have appeared in several publications over a period of years:

The Phallus

Tiger (aka Tiger Man)

The tattoo on his left forearm looks like a scale with three lines over it. Tattoos were rare in 1968, unless you were in the navy.

That uncut cock is rare for Americans of the Baby Boomer generation.

He's not very muscular.  That's a 30-pound dumbbell, and he needs two hands to lift it.

He was living in Portland in 1968.

He's reading a straight porn magazine, so he's straight, or at least that's the impression the photographer wants to give.

He looks a little younger in this black-and-white photo. Probably from 1966 or 1967.

They only had nude photos in physique magazines beginning around 1965, so this twink was an innovator.

That's all I know, except that Rick Dion was publishing out of Portland, Oregon.  Box 73 at the One Institute Gay Archives contains some samples of his models: Rene, Race, Tuck, Scott, Pete, Gary, Rod, Kurt, Jack, Cy, Randy, Shannon, Mike, Lee, Pete Shea.

And Tiger Man was published in L.A.

And there's a buffed Bollywood actor named Tiger Schroff.

Dig the old-fashioned telephone.

There's a Michael O'Donnell at Rockefeller University, who got his B.S. in Biochemistry from the University of Portland in 1975.  Around the same time, and he has the same jaw.  Connection?

Probably not.  I imagine that this well-endowed young ex-sailor vanished into the youth counterculture without giving anyone his real name.

Anybody know who he is?

Nude Photos of Craig Sheffer, Maybe

57-year old Craig Sheffer is a dramatic actor most recently seen on The Mentalist, CSI, and Psych. But back in the early 1980s, he got his start in the soap One Life to Live, the Brat Packer movie That Was Then...This is Now, and Voyage of the Rock Aliens (1984), a weird Ziggy Stardust- Grease pastiche about rock-and-roll-playing aliens invading a high school.  He played some sort of David Bowie-John Travolta rock god with nice abs.

Around 1982, Craig was photographed by pop artist Andy Warhol, who of course liked photographing gay, bi, transgender, and gay-for-pay men.

He photographed Shaun Cassidy around the same time. 

Several photos of Craig have appeared, including some purported to be him nude and aroused.

I'm not sure. This guy is quite hairy, and Craig is smooth.

And what 22-year old wears a cock ring?

Oh, well, at least the cock is impressive.
