The sketch is based on a photo taken a few days ago while casing the crowd at the annual Woodward Dream Cruise this previous weekend. I was looking for subjects to draw. There were venders set up all over selling things related to the cruise. I know: where are the cars?.
I found these three more interesting contemplating items to buy.
