There are two Jim Thorpe postcards in the 1912 set. Fortunately, I have both. The other one is card #99 and features the start of the 1500m in the Pentathlon. In 1912 there was the Modern Pentathlon, which is still competed today. Gen George Patton competed in that one in 1912. There was also the athletic pentathlon - long jump, javelin, 200m, discus and 1500m. This card is much harder to find than #238, the one shown in this thread.

Avery Brundage - he did not finish this race. Best known as president of the International Olympic Committee, he was an accomplished athlete in the 1910's. He finished second in the AAU decathlon championship in 1915. Alma Richards, the man who beat him, was the high jump gold medalist in Stockholm.
