Automobile racing on board track speedways began in 1910 at the Los Angeles Motordrome and ended in 1931; during this period thirty-one of the wooden tracks were constructed around the country. This photo via Isabelle Bracquemond appears to have been taken at the Cotati Speedway, a 1-1/4-mile track located in the city Santa Rosa in northern California; it was in operation for only two years between 1921 and ’22.
The Buick “Aero Car” was possibly sponsored by both the local Buick dealer and the Speedway as some of the lettering the tail fin says “Going to Cotati Speedway.” The body of the car appears to have followed aircraft construction as the side of it is covered with painted fabric. The rear of the chassis is equipped with cantilever springing, and the six-cylinder o.h.v. engine is located about two feet higher than normal and may have powered a transmission mounted below by chain drive.
The chain driven “Baby Car” on the left-hand-side of the photo is of the type as has been seen earlier on The Old Motor and appears to have been built in the same manner as the miniature Art Smith racing cars. More can be learned about small cars of this type in earlier articles.
