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. :)
(Blue biro on 125mm x 75mm notecard) A third in the guardian spirit works that I've done. When it comes to these kind of things, who wouldn't prefer a pistol-packing angel like that?
Doodle with Pentel brush, and posca! A little bit note to self. "In between goals is a thing called life that has to be lived and enjoyed." by Sid Caesar.
