Let's do a few this time:
January 18: This strip is a callback to December 16, 1953.  Like that earlier strip, Schroeder's legs reveal attention to how they're braced against the fence.  Nowadays it seems weird that a kid would get off of school for his birthday, or that of any random classical composer.  That fence is weird -- it's in both strips.  This must be the edge of Schroeder's yard.  Chagrimace!

Of note for trivia contests: Schroeder's birthday is January 18.

January 19: It would be so easy to derive a political message from this strip.

January 20: This strip is something of a callback to July 2, 1953.  In that strip the kids are saddened by the prospect of being left with a babysitter.  Here, they're gloating at the prospect of the other being left behind.  Gradually, their relationship is evolving.

January 21: I like this one for how the shape of the notes in the last frame fill in the space between the top and the piano.

December 5, 1953: Reciprocal slobber

Read this strip at gocomics.com.

There are a few strips that notice a basic similarity between the behavior of very little kids and dogs, and by my reckoning this is the first.  I seem to remember a few strips that played this up when Sally comes on the scene, when she and Snoopy team up to steal Linus' blanket.

Why is the noise of Snoopy licking depicted as "smack," and why is it in a word balloon?

When characters stoop over, like Lucy is in panel three, it seems easy to imagine them unfolding their legs and ending up much taller than they should be.

August 6, 1953: The weirdness of Patty's dress

Lucy exhibits surprising self-awareness here.  She loses these introspective powers as she comes into her own as neighborhood terror.

It's worth noting, for a moment, the bizarre attributes of Patty's dress. All the girls typically wear skirts in this phase of Peanuts' development. Some time earlier, when a girl bent over Schulz didn't bother to wrap the skirt around the legs. In this strip, however, he cheats Patty's legs and skirt longer as she stoops down to Lucy's height.

Even more interesting, however... look at the cross-hatch pattern on her dress. Does something look odd about it? It's like the cloth is a shaped hole in the paper, revealing the pattern behind it. Due to the small size of the panels on the page, I think the pattern reads better this way than if it were more realistically drawn.

I love it when comic strips do things like this. A contemporary example, to borrow from outside the artform for a moment, is in the Monkey Island series of computer games. Most of them feature a salesman character named Stan who wears a loud checked sportcoat. The pattern on the coat is applied across the folds of cloth in much the same way as the pattern on Patty's dress. This fan drawing on Stan (taken from here) illustrates the effect:

Recently the series made the jump to polygonal, 3D graphics. The pattern on his coat is considered to be such an integral part of the character that the developers went to special trouble to preserve the effect (source page):
