This is a postcard promoting the Roller Woody and Sleep Machine yo-yos by Tom Kuhn. These yo-yos were released concurrently in 1992. On the back there is general information promoting other products.
This a 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.
