"Some of the most flamboyant, and expensive coachwork
ever to come out of France was created, or caused to be
, by expatriate russian cabinet maker Jacques Saoutchik.
In 1948, noted New York city furrier
Louis Ritter commissioned Saoutchik to execute
a special convertible on a Cadillac chassis. The car was
completed in time to be displayed
at the Paris salon of 1949."
