How does someone with a face covered with hair blush?
Looking at Violet walking here, she looks very similar to the style of the characters for the next few years. She's almost at the proportions of classic Peanuts now. Charlie Brown is the human character who still looks the most like the original, with his oval head and thick eye-dots. And Snoopy takes still more time, and doesn't get to the familiar look for many years.
Turnabout strip! What does it say about the Peanuts world that chasing someone, presumably to inflict violence, happens so often?
