What a terrific photo -- two prime portions of beefcake, flexing and smiling just for you!
Of course, the young man on the right is icon Glenn Bishop, but who is that on the left? I'm 95% sure that it is Tim Sweeney. Since both Glenn and Tim are known to have been photographed by Cliff Oettinger, I'm going to attribute this photo to him. If anyone can confirm or deny my guesses, please feel free to write me!
