One of the first industries we worked with back in the late 1980’s and into the 1990’s was the collectible industry. We worked with both the Franbklin Mint and the Danbury Mint. We Designed, engineered and Prototypes many 1/24th scale Die Cast Vehicles. We would find the most accurate vehicle and send out a team to document it. The model would be drawn in pencil on vellum. This was before the advent of CAD. Then the prototype would be carved. Much of it was carved out of a single block of acetate.
