The Oakland Roadster Show Diorama consumed more than 2,000 hours among its principal planners.
In addition to the incredible time commitment by master modeler Ken Hamilton, lists of scale model customs had to be developed, research had to be done, fund-raising had to occur. In short, the continent-spanning
effort (the Diorama was constructed in New Jersey) involved dozens of modelers from the United States, Canada and Australia. The Diorama was dedicated to Bob Barnett, just three short weeks before his death in 1994,
when Gustavson, Wick and Hamilton took Bob to the Museum and, there, unveiled the Diorama (with Bob's name affixed just above the front opening); despite his early role in conceptualizing the Diorama project and
doing much of the historic research, Bob had never seen the Diorama prior to the time he traveled to GSL-XV in 1994.
