Great drawing! I think you're referring to the use of white out against colored paper. Something I've been doing for a long, long time. You can check out the Drink and Draw book which was published in 2006 from Image Comics. It compiled a bunch of illustrations by myself along with & and a bunch of other guys drawn from 2005 on. I'm not sure, but I think the trend kind of caught on. I'm not saying we were the first artists to use that technique - but I am saying that nobody published or posted illustrations done in that style previously.
