All Star Dairies commissioned this machine to promote the company's Batman and Robin milk. The owner originally built the car between 1961 and 1963 using an Oldsmobile chassis - complete with a 350 V8 - and a custom fiberglass body, and the dairy company approached the owner to lease it for two years to promote its comic-themed products. That makes this creation the world's first Batmobile, preceding the famous 1966 TV Batmobile by two years.
