Mike, the Packer HOF told me that very was produced and little survived from that era. I think the "holy grail" would be a 1910s Jim Thorpe Carlisle or Canton Bulldog card. Maybe one will surface in our lifetime. Here are few 1913 Green Bay Town Team photo/card I was fortunate enough obtain. These guys made it to the original 1919 Packer NFL team. Jim Coffeen was the Packers first quarterback and became their announcer.
