Victor Regal was a famous racing rider and driver whose career began in 1898, winning the Levassor Prize in 1901 and numerous other races and records over a 25 year period in Europe and the United States. He was also a pioneer aviator.

His younger brother, Louis Vidal, also became a racing driver in the 1920 and 30s.

(The caption says it's Rigal, but it looks very much like Lamberjack)
