Perfect Duluth Day

Mystery Photo: Drag Racing on Lake Superior

Allouez Bay in Superior was recently the scene of a stock-car racing event, which might have seemed like a newish idea, but … the undated photo above has a handwritten message on the back that reads: “Taken on Lake Superior. Duluth in distance. Thousands on ice at time of races. A new sport. 24 in. of ice at time.”

So when did auto racing on ice become a “new sport”? Can anyone help put a date on this photo?
