When I first saw these Portland cabinets offered, I thought that it would be nice if they were kept together as a set. As it turns out, it appears that I was the one who broke up the set....

I managed to win the Jim Rogers and Billy Annis, and he apparently won all the rest. I am glad to have learned the photographer's name, Charles E. Jackson. He notes that the players names are also written on the backs, which looks to me to be in the same hand (i.e.- not autographs). The cabinets should arrive this week and I will post some scans.
