The personal Avanti of Raymond Loewy will be auctioned off by Bonhams on May 11. Legend has it that this car was designed on a cocktail napkin by Mr. Loewy while in Palm Springs. Who says you can't mix business and pleasure? This is the second Avanti belonging to Loewy to be auctioned off in the past few months. This particular vehicle resided at Loewy's Parisienne address.
