On Facebook the Charles M. Schulz Museum is featuring the 9th Sunday installment of Peanuts, originally published just a month after Monte was born.
In 1952 Schulz was still inking lines with a brush, before switching to a pen. The characters hadn’t yet developed their individual personalities, but Chip Kidd has commented on Patty’s fascination with mud. Note that Kidd gets the year wrong.
The third Peanuts collection, “Good grief, more PEANUTS!” was the first with Sunday strips. Published in 1956, it doesn’t include the 3/2/52 strip.
