Another chase here, after Charlie Brown slyly insults Patty, who is beginning to show almost Lucy-like characteristics of ire. Also, check out Charlie Brown's Shakesperian posing in the third panel. It's best not to compare the length of his arms to the size of his head here.
Another thing to notice here is that the characters, viewed from the site, don't look tremendously different from their modern incarnations. When we get a head-on or three-quarters view, however, they'll still look fairly alien.
