Art made of various parts and pieces, 1972, Don Potts, "My First Car"

It was shown in galleries, but it seems his agent got greedy, and Don wrote a long article about the process... but had his art crushed in a crusher instead of selling any of them. That cool motor? A McCullan drone engine. Yeah, I had to know!

Road and track magazine described the art this way :

THE FIRST CAR of Don Potts is actually an extraordinary assemblage�a concours d�elegance of one man�s work. The title itself has a sort of parallel to Tom Swift and his Electric Runabout and the objects themselves are resonant with the objects of a now�lost American boyhood�an American Flyer wagon, a soap box derby car, a first bicycle�but here raised to the Nth power of imagination.

The craftsmanship is literally stunning--but it is no more important to know that Potts�s spent six years on this creation than it is to know Michaelangelo�s back bothered him in painting Sistine Chapel. The Potts car is simply there in ultimate perfection.
