I came across this group of memoribilia at a recent estate auction. In the auction, I purchsed 2 Saint Marks football team photos, 1 panoramic photo with six individual mounted photos, 2 individual St. Marks baseball player photos, and a 1907 Spalding Trophy football.
The football has '07 painted on 2 panels of the football on 1 side. The other side has written on it: (difficult to read) St. Marks Military C
October 1, 1907.
The ball is a spalding ball, but I can't make out the model number in the pump area between the laces.

Anyone ever heard of a Saint Marks Military College. I can't guarantee the word after military is college, but it looks like it starts with a C.

Another SM team photo that I missed out on, had a Chestnut Street address for a photographer/gallery label on the back of the frame. This coupled with living in a Philadelphia suburb, I seem to think it is from the Philly area, but I could be wrong.
My recent research hasn't been able to uncover any Saint Marks Military College, but I'll keep trying.

Any ideas?
thanks
