January 20, 1953: Snoopy and Schroeder

I think this is the first strip with just the two of them. Later on there are some memorable strips that pair the two that I, um, don't remember at this minute. Heh.

How large is Snoopy in the last panel? The more I look at it, the more he seems to be huge! We know the kids have to reach up to reach the door handle, and as this strip shows Snoopy is still pretty small relative to them. But sitting down in the last panel, his head come up most of the way to the door! Am I just seeing things?

November 4, 1952: Linus' head is too big, #1

There are a number of these strips that deal with baby Linus' head weighing him down. This is but the first.

November 10, 1951: The claws come out

Another unexplained burst of rage from Patty and Violet, who in later strips would become almost defined by their disdain for Charlie Brown. When I was a kid reading 50s and 60s Peanuts strips in compilations, I thought the characters existed mostly to hate him.

This one implies that the two characters were reacting to something distasteful Charlie Brown did. Is it possible that the characters were always considered to be reacting to something CB said, offscreen, but in later strips the setup was just left out to save space?
