Bugatti Type 57 cabriolet, chassis 57587, bodied by Letourneur et Marchand to their design number 5877 and identified as the first of eight such bodies built to that pattern. Originally commissioned by Baron Georges de Cocq in 1939 with bespoke modifications including an extended steering column and a custom fishing-rod holder, the car has documented provenance from new through a succession of prominent American collectors.
