Dodge Tradesman Maxivan is the van, which Feynman bought in 1975. The colours of the interior were 'mustard-yellow' and 'avocado-green', and outside it was decorated with his famous Feynman diagrams. The license plate was QUANTUM. Feynman used this vehicle to travel to and from work while he was a professor at Caltech, and to explore remote areas of the American West with his family during summer vacations. Source: Fermilab
