Here are a few photos of Porter from my archives. The captions on both are dated 1909 though one shows him in his Cornell sweatshirt and the other in his 1908 Olympic uniform. He probably graduated from Cornell in 1905 where his best finish was 2nd in the IC4A championships. He won the gold medal in the high jump at the 1908 Olympics in London. He was the #1 ranked high jumper in the world in 1909. One of the captions notes he was a Christian Scientist. Looked at a lot of the cards on ebay and I have original photos of most, if not all, of the Olympic athletes in the set.

This is a photo of the photo after it was marked with highlight/masking paint. His face looks almost comical. The rag tied on the high bar was a common practice and legal back then. You can also see it under his leg on the card.
