Thurber, a writer and editor for the New Yorker magazine when it was at its best in the 1930s through the 1950s, couldn’t draw worth a hoot in the conventional sense. Yet he loved to create doodles of floppy-eared dogs, timid men and dominant women and some of the editors insisted these be in the magazine.
...Many times his cartoons came about because he didn’t have the skill to draw what he initially intended. The classic first wife/present wife cartoon came about because he couldn’t draw the perspective of a stairway. The seal cartoon here didn’t start out to show a seal behind the headboard of a bed but it ended up that way.
...Thurber’s obvious limitations irritated some readers and even other cartoonists. A cartoonist once wrote a letter to Harold Ross asking, “Why do you reject drawings of mine, and print stuff by that fifth-rate artist Thurber?”
“Third-rate,” Ross replied.
