Young Wrestler/Strongman in Prize Belt and Balletic Pose, Antique RPPC (with Bloodstain on Reverse)

I take this handsome and very poised looking young man as a wrestler, 1st decade or so of the 1900s, with what looks like some manner of prize belt around his waist, though I can't quite read what's on it. He seems to me, though, with arms and feet in first position, ready to rise on his toes and spring to life as a ballet dancer. A charmer.

5 3/8" x 3 7/16" and in overall good condition, general wear and what appears to be an old blood stain (!, with fingerprint) on the unused postcard back.
