Scott,
Very cool display. Since you are a Harvard guy I am posting two 19th century Harvard autographs from my private collection.
William H Lewis - 1891-93 Harvard center, first African-American All-American and earliest college football HOFer. He became a prominent lawyer and was appointed to US Assistant Attorney General.
Charles D Daly - Harvard All-American QB from 1898-1900. Transferred to Army on request from Teddy Roosevelt, where he played from 1901-02. Considered the only 5x All-American football player and inaugural member of the college football HOF. I was blessed to purchase his personal estate from his grand-daughter, which is now in the West Point Archives. I kept a couple autographs and a beautiful handpainting by him.
