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. :)
This is the first little 'Thumbodies' character that I designed during the holidays. She has many other kind, creative & adventurous friends! Online comic & doodles @ doodletowncomic.com
