The very first Duesenberg Model J, with engine J-101, made its debut on December 1, 1928, at the New York Auto Salon. Built as a factory demonstrator, it was created to showcase the unmatched power, performance, and craftsmanship of the new Model J line. Legendary engineer Fred Duesenberg personally toured the car along the West Coast during the 1929–1930 auto show season, presenting it as the pinnacle of American automotive innovation.

The car remained in the Duesenberg family, owned by August Duesenberg until 1955. After that, it passed through several well-documented owners, including Tiny Gould and Bob Adams. In April 1974, Walter Spilsbury purchased the car at an Atlanta auction and actively drove it for a decade before selling it in December 1984 through Tom Barrett to Mrs. Lyon, who acquired it as a gift for her husband, General William Lyon.

With its striking Sweep Panel Dual Cowl Phaeton body by LeBaron, this car stands as a symbol of prewar elegance and engineering excellence and as the very first Model J ever built.
