what a publicity seeker, Art Smith and his Harley powered "Comet" were at the launch of the Dole Air Race in California - because all the news press people were there, and he wanted to horn in on the free publicity with his Baby Cup racer

Aviator/daredevil/publicity whore Art Smith in his Harley-Davidson powered Baby Cup race car built for board racing by Maggini & Perkins at the 1915 Panama-Pacific International Exposition (PPIE) in San Francisco.

I posted about him https://justacarguy.blogspot.com/2018/05/art-smith-famous-for-being-young-stunt.html  and did a better gallery of the car at a recent concours https://justacarguy.blogspot.com/2011/07/balloon-tires-so-big-they-look.html with a video of it racing
