This is mostly notable because it's Schulz engaging in more metacommentary about comics.
One of the more insipid trends in Peanuts is those cloying "Happiness Is..." pictures. I actually don't think they were ever that prevalent in the comics; I think they were used more in books and merchandising. Still, this is a step in that direction. It is also the first instance, to my eyes, of Charlie Brown bemoaning his fate in the recognized Charlie Brown manner.
I think that would actually be a funny strip, in a New Yorker kind of way. (Which means other people probably wouldn't think it'd be a funny strip.)
