Every time I'm in NYC, I end up drawing oodles of people and giving them out, like picture satellites, on napkins, paper scraps, pages from my sketchbooks. Its a great way to gablessly schmooze, but people are way less annoyed if you give them a doodle after you've been candidly grilling them for 10 minutes.

Unfortunately, It leaves me empty handed at the end of each trip...and lacking reference to some great memories. So this time around I brought carbon paper. aside from giving me a carbon copy, It recorded every mark, scratch, mistake. The loose sheet of carbon paper jerked around the page a little as a drew.
By the end, my alternative versions grew on me, slow-shutter drawings of people in motion. Draw on agitation.
