The great Olympic Weightlifter Humberto Selvetti shows his stuff in his home land of Argentina. It was Selvetti who Paul Anderson defeated to win the Gold Medal at the 1956 Melbourne Olympic Games. Selvetti and Anderson both totaled 500 kg but Anderson beat him on lighter bodyweight)
Selvetti also competed at the at the 1952 Olympic Games in Helsinki (where he took Bronze with a 432.5 kg total) and at the 1964 Tokyo games, (where he finished 17th with a 445 kg total ).
As a side note, I find two other items of interest in this phone, #1, that’s a pretty hefty weight to put overhead while going uphill, and #2, the barbell set in this picture is especially unique, I have never seen anything like it before or since.
