While Peanuts creator Charles Schulz was certainly known as a all-around wonderful, decent guy, there's no doubt he had a mischievous, smart-aleck side to him as well. Consider for instance this letter, recently donated to the Library of Congress.
In the letter, written in 1954, Schulz addresses a Ms. Elizabeth Swaim, who had recently written the cartoonist to express her distaste for the then new Charlotte Braun character, a loudmouth Charlie Brown lookalike that Swaim was not alone in disliking.
Schulz tells Swaim that he is taking her advice and getting rid of the character, but then reminds her, "Remember that you and your friends will have the death of an innocent child on your conscience! Are you prepared to accept such a responsibility?"
And, in the interest of driving his point home, he draws a picture of Charlotte Braun with an ax in her head. Wonder why that never made it into any of his "Happiness is ..." books?
