Don Treadway held his first auction in 1980 after five years as a private dealer exhibiting at shows across the US and Europe. 1987 brought the beginning of a 30 year auction run in Chicago, creating a presence in the art and design movement world wide. Treadway, from its beginning, was the first auction house to not only specialize in the 20^th Century Design Movement, but also guarantee the objects they sold. Today they continue that tradition of providing outstanding customer service and record-setting results.
