The main reason this one is here is because it is the first strip appearance of the famous Peanuts logo in the first panel. Later on it'd get the words "Featuring 'Good 'Ol Charlie Brown'" beneath it, but those are a long way off.
In the intro panels, Charlie Brown seems a fair bit more affectionate towards Snoopy than you'd expect a non-owner to be. Concerning the content, well, these were the days before political correctness. At least Patty is allowed in the game.
Also seen here is one of the relatively few childish mispronunciation gags in Peanuts. I am referring to Charlie Brown's mentioning Shermy and Patty wouldn't be interested in a "Treace Peaty." This Sunday strip is, like some of the other Sundays we've seen so far, basically a collage of jokes erected to pad out what would ordinarily be a weekday strip. Schulz doesn't seem to have yet learned how to pace these longer comics.
