Bob Haro has had a pretty big influence in my life. One of the things that attracted me to devour BMXAction more than BMX Plus! was the illustrations by Haro who was on staff at BMXA.
Haro is also known as the originator of BMX Freestyle. A type of riding I took up in my teens because my parents wouldn't take me to race. I learned a lot of tricks by trying to copy what I saw Haro do in photo spreads in BMXA.
Haro is the man behind the Haro brand, starting the company by hand cutting and forming number plates while watching the 6 Million Dollar Man on TV. He then went on to do some other accessories, but finally it was the Haro Freestyler in 1982 that really got things going crazy. It was the first frameset designed specifically for trick riding. Within a couple years every BMX bike maker had to have a freestyle lineup, or didn't sell.
Besides being a freestyler and entrepreneur, Haro was also heavy into illustration and graphic design. He created the graphics starting with his number plates, clothing and into the fresh-bold graphics for his bikes. I think some of the thought he put into the design of things left an impression that in part led me to following graphic design myself.
I'm no illustrator, I could only wish to be able to pencil a sketch as well as Haro.
I found these illustrations all over the internet. There are a ton more. Just do a search for Bob Haro Cartoon, and you can find bunches.
Haro has a couple (maybe even more then these) of sites. Looks like one will revolve around his BMX endeavors (BobHaro.com), and the other, his design group (Haro Design, harogrp.com).
