One of my favorite styles of aviation drawings, is completing them on paper towels. I also use napkins as a means in sharpening up my skills due to the delicate materials involved, & the drawings albeit a bit challenging & labor intensive, ways come out to my liking, as well as to the liking of others.
Here we have pictured one of my favorite airlines of yesteryear which I love drawing, the original Eastern. Such a kool-looking airline, and such handsome-looking aircraft!
