1950 Delahaye 135 Cabriolet Atlas by Guilloré
- Colour
- Original period blue

Chassis 801636 is a Delahaye 135 bodied as a Cabriolet Atlas by the coachbuilder Guilloré, one of no more than five examples constructed. Believed to have been the actual Paris Salon show car of October 1949, it remained in France for decades before a sensitive mechanical restoration was carried out in the 1990s. Subsequent cosmetic work was followed by concours appearances, including the 2011 Pebble Beach Concours d'Elegance, making it one of the most publicly exhibited survivors of this rare coachwork.
