His slides (taken with a Yashica camera, he notes) show the unusual cars in the nice, bright colors of Kodachrome.

The influence of the Essence is most apparent in the sedan's undulating character line and the way that the hood plunges down to meet a low-set front grille complete with concave outer edges.
