May 21, 1953: On the mound: The origin of the pitcher's mound

This is the first strip in which there is an actual pitcher's mound, and not a flat spot of earth. Of course the later mound is a lot wider, but it's not actually much shorter.

One flaw with the premise of this strip: when the other team is up to pitch, wouldn't it help them just as much?

May 13, 1953: Baseball Blockhead

First use of the word "blockhead." Also, the first strip in which another character comments on Charlie Brown's lack of pitching skill.

Sunday, April 19, 1953: Shermy Pitches

In this early baseball strip Charlie Brown's team is losing even though he's catching this game.

Look at that first panel for a moment. There are six kids pictured. Counting from the left, it's hard to tell who the second and third ones are. The second kind of looks like Charlie Brown, and the third like Shermy, but they're already in the shot viewed up close. This would make these two kids the first "extra" human characters in all of Peanuts. (Animals have had a couple of extras so far, an anonymous dog and a bird.) Some of the other panels have unknown extras too, as well as Lucy and Schroeder a couple of times.

October 1, 1952: HA HA METAHUMOR

Peanuts has sometimes been taken seriously by folks, including Schulz himself, but there are moments like this every once in a while. There isn't really any connection, other than motive, between Schroeder's discovery and his remarkably knowledgeable comment. I can picture Schulz laughing at the idea of a character annoyed at being in a comic strip and looking for any excuse to work it in.

April 12, 1952: Ball One

Poor Charlie Brown would never really get much better than this. This is the first strip that puts both Charlie Brown and Schroeder into their respective baseball positions as pitcher and catcher.

Of special note: Charlie Brown's pitcher's mound is a lot more subtle in this strip than it would be later on.
