This is the converted school bus that belonged to Route 66 super sketcher Bob Waldmire (RIP). It's here at our museum, so I sketched it one day. It's an amazing studio/home on wheels!!
This is old (2007). I used to work at the ad agency that had the Harley-Davidson account for a number of years. I always carry around a Moleskine sketchbook and take meeting notes on one side while doodling on the page next to it. This doodle ended up being used extensively in the Harley-Davidson "Dark Custom" campaign as well as on a line of Dark Custom Motorclothes.
It say's "FUCK YEAH" in it and they never noticed. :)
