logo and the Santa Cruz Skateboards logo that can still be seen as a sticker on local cars.

But Jim could always put pen to paper to anything, and did it ten times more uniquely than any other at that time. Even when the computer world decided to step into change the way graphic art was formed, he was always one step ahead and took the changes by the horn with great success.
