This turned out to be 1956. The Arrow Lakes Historical Society (in my little village of Nakusp) discovered some film from the mid -1950s which included a segment on a baseball game in Nakusp. The material was filmed by Nakusp resident Ichiro Shiino who thankfully sent a copy to the Historical Society.
It was a film mainly about the July 1st celebration, but at the end had a segment on a baseball game. I immediately thought about asking Lou DeRosa, who played in Nakusp in that era, if he could identify any of the players, especially the Nakusp pitcher.
Lou was blown away. As, he could clearly ID the pitche as ... Lou DeRosa.
