Monday Cartoon Day.
In the sixties one time Batman artist, Mort Meskin collaborator, New York School of Art Comics instructor, comics book artist and illustrator Jerry Robinson, took to cartooning as his way of making a living. But he kept his realistic background. Although the humor of Cassroom Flubs and Fluffs (illustrated puns inadvertantly made by kids and sent in by their parents) may have seemed a bit old hat even when he came up with it, it looked great. Hre are some samples, I have many more to scan.
