This is me, six years ago, at R. (I call him Bob) Sikoryak’s Carousel. In its simplest terms, cartoonists project their work on a screen, and then “act it out.” (Way back when, Bob used slides, so “Carousel” actual referred to slide carousels. Ask your parents.)
I had been working on a pantomime comic called Infant Fred which, having no words, made it tricky to act out. So, obviously, I tried to escape from a straight jacket before 25 drawings had been projected. (You can see if I succeed at the link below.)
