June 4, 1951: Man of the earth

Notice the difference in Charlie Brown's mouth when seen in three-quarters' perspective (second panel) and nearly full-on (fourth panel).  On the first we get a relief line, the second just a mouth outline.  If Charlie Brown were seen straight-on, Schulz would have had to figure something to do with his nose, as his U-shaped noses would have to pick a side to be seen from then.
