Jeff: That is my favorite photo of Yost. As a huge Michigan collector and fan, you couldn't post a better picture on this forum. Very cool piece. Congrats!
Eric: Osgood is not in that photo, but he was on the 1893 and 1894 Penn teams. Here is another 1894 Penn photo I acquired from the George H. Brooke estate. Brooke is seated in the center, middle row. Osgood is to the left of him.
