This is a sketchbook assignment I've given students to help them think about the city around them. We all have seen the food trucks or other businesses housed on four wheels, and maybe we've tried the food or bought the goods... but now, it's the students' turn to design a truck. Think of a product or food item, then design the truck.
This was inspired by a short magazine article I found (in addition to seeing the trucks more and more often myself), which I scanned and added to the handout for students to view.
My art one students have found this to be a challenging and fun drawing to complete.
