When I was in junior high school, I learned to draw simple cartoons. My mother had several artistic talents. She painted and drew, and could play several musical instruments. But my real teacher in the drawing of cartoons was a kid in my neighborhood, Leal Mallory.
Leal lived down the street from me around 1956 when I was a freshman in high school. Leal used to draw cartoons all the time, and I learned to emulate his style with creations of my own. His cartoons were actually a lot lot like some of the drawings in Mad magazine, which was very popular at the time. Leal was a big fan, and he had a very complete set of copies.
By 1957 Leal moved away, and I never saw him again. He died in 1976.
My cartoon above is similar to what Leal drew. We call him Boris.
The following cartoon shows one of my attempts at a self portrait.
And finally, here is a letter I wrote in 1972 with cartoons included.
