An interesting photo of Eddie Wendt who was a West Coast midget car driver. His car appears to be motorcycle engine powered, possibly by a v-twin as we can see one-air cooled cylinder thru a hood opening. Midget car racing started in California in the mid 1930s and became very popular throughout the US. After WWII, midget racing developed into a 7 day a week craze in front of huge crowds. Even many Indianapolis car drivers became involved.
By 1950 the craze was over, stock car racing became more popular, and TV entertainment in the evenings also cut down on the crowds. Even so, midget car racing still exists today.
