9MC 1923 Roodhouse, Illinois

Operator: Albert Henley Cain
QSL also has the call sign 9DNW on it and the QSL says that call sign is used by Junior Operators.
9DNW was actually licensed to Wilfred W. Fraley, also of Roodhouse.
QSL says Mr. Cain was a Ford Dealer. He also held a few patents related to the automotive industry.
It seems he had quite the station and was heard worldwide. There were several writes ups on Mr. Cain in magazines in the early 1920's.
