A couple of years ago I engaged some people in a collaborative sketch project on DailyBooth. It was kind of like my sketch-it project from 2006. I asked people what they wanted me to draw and I drew it for them in a relatively short turnaround. Since I still have them, I decided to send them out into the world as Return2Me postcards.
Look for them around Minneapolis. I may make some prints of my favorites and ship them out to some volunteers. See the rest of the Hand Drawn postcards here.
