Calder's friend, Herve Poulain, a French auctioneer and race driver, asked him to commission a rolling canvas on the BMW 3.0 CSL he would race at Le Mans 24 Hours race.
An engineer and sculptor, Calder’s challenge was creating his own "artistic stamp" on something that he did not produce and sculpt himself. His rendition of the 3.0 CSL boasts powerful colors and attractive curving expanses, which he applied generously to the wings, hood and roof. Calder saw his art in action when he attended the Le Mans 24-hour race as a guest to witness his work’s premiere.
