This is one of the many postcards that Tom Kuhn yo-yos sent out promoting their yo-yos. This postcard promotes many different products for "World Class yo-yo fun." There is also some very neat information on the back promoting other products.
This is another great example of early Tom Kuhn direct marketing. For many years the main way for many people to buy Tom Kuhn yo-yos was through their mail-order shop located in off of Haight-Ashbury in San Francisco.
