Al G. Barnes with Abbott Kinney for what some say was a publicity stunt. Kinney was the founder of Venice of America where the Barnes circus wintered from 1911 until 1919.
There was no writing on the back of this photo, so I am not sure if this is Ringling or Barnes. Casper also worked for Sell-Floto in 1910. The original is in poor condition, so this is the fixed version.
