The Pontiac advertisement illustration above was part of a famous 1959-1972 series. The car was illustrated by Arthur M. Fitzpatrick (1919-2015), Wikipedia entry here. The background was by Van Kaufman (1918-1995). It is of the Monte Carlo casino in Monaco.
Early in his career Fitzpatrick worked as a car stylist at Briggs (which made bodies for carmakers) and Hudson as well as "Dutch" Darrin's California organization. After World War 2 he shifted to automobile advertising art, delineating vehicles for advertisements and brochures.
A new book titled "Art Fitzpatrick & Van Kaufman: Masters of the Art of Automobile Advertising" arrived in my mailbox a few days ago. Here is the cover:
The website for the book is here.
Illustration Magazine issue No. 73 has some material on "Fitz" and "Van" by the book's author. And the book's website has some sample pages for your inspection.
