This brings to a close the second year of the strip.
In the second year were introduced both Lucy and Linus. Schroeder learned to talk. Charlie Brown's psychological problems began to become more evident. Shermy, already on his way towards irrelevance, only appeared a small number of times. Schulz's art style, fired in the crucible of a daily comic strip, has evolved considerably. Most of the characters have gradually eased into their classic looks, all except for Charlie Brown (who's oval remains as a vestige of the original style), Snoopy (who has so far changed fairly little) and Linus (who is currently the strip's baby).
In the next year there aren't any major character introductions, but Schulz's art style evolves a bit more. Snoopy and Charlie Brown both draw closer to their later forms. The very next month has the first of the strips where Charlie Brown fails to kick Lucy's football. But most importantly this is the year in which Peanuts' writing really matures into something recognizable and wonderful.
For comparison's sake, here is the strip from one year before:
And here is the strip one year to come:
