I came across another terrific set of photos from conceptcarz.com. These images are of the Buick "Bug" racer - allegedly the one "Wild" Bob Burman drove several victories in 1910. The sister car was driven by Louis Chevrolet who also enjoyed tremendous success.

One of my favorite sites for race car photos, Conceptcarz.com, has an excellent collection of photos of Ray Harroun's winning car from the first Indianapolis 500, the Marmon Wasp.
 

This video is the fourth in a multi-part series on the history of auto racing and primarily focuses on the Indianapolis 500 from 1919 through 1921. The footage is absolutely fantastic, with several scenes of what would be unthinkable today - drivers and mechanics pushing disabled cars along the inside apron to get them back to their pits.

I discovered a Web page presented by auto racing historian Don Stauffer that has some excellent copy and interesting photos of early track racing in Minnesota. Check out the photo of Webb Jay and his racer, Whistling Billy, as well as the J. Walter Christie's massive front wheel drive racer.
