College sumo wrestling is an integral part of the professional sumo wrestling. Many college sumo wrestlers hone their skills at this level and then enter a professional sumo stable to train with the elite wrestlers. These elite wrestlers have been captured on cards, menko, bromides, post cards, and all sorts of ephemera since the late 1800s. However, college sumo wrestlers received no such honor or glory. However, I finally ran across a small set of 1930s college sumo wrestling menko, but know little to nothing about them except for a few last names.
I see Asami (9700) from Keio University, Horiya (1000) from Namisho Commercial, and Minobe (6400) from Tennoji Normal School along with a gyoji card (3410) a few cheering spectator cards.
I hope to do some more research to figure out exactly what I have here, but any assist would be greatly appreciated!
