I’m not sure the way I found this excellent page on Karlis Ploks – 1930’s Stunt master, however, this photo is incredible. Born in Seminole, Vidzeme (Latvia) in 1895, he increased up poor, offered in WW1 and wound up your gypsum factory in Riga, Latvia. After a little operate in Odessa, Russia, Karl moved to Riga and required to doing what he loved – as being a motorcycle stunt king. Cheers Karl, you are appreciated.
