Michael Knab founded and operated an advertising agency in Chicago for over 30 years. Among his his many well known clients was Revell Monogram, the toy model company. His passion for automobiles lead to launching the Diecast Zone, one of the first online hobby community sites. The audience was geared toward collectors of precision scale model cars and trucks. Soon Michael created Legacy Motors, which became the leading online retailers for scale model cars, trucks, motorcycles, and military vehicles. From there he created an art gallery called Legacy Motors Automotive Art Gallery. Today his focus is dominated by his online art gallery representing the best automotive artists of today at Legendary Cars Life.com.
