The Complete Peanuts, Vol. 8: 1965-1966 by Charles M. Schulz

Peanuts rolling along. Charlie Brown goes to camp for the first time; later, so does Linus. Snoopy becomes a WWI flying ace -- and "A dark and stormy night" makes its first appearance, for a sequence of about a week, after which he, having dragged his typewriter to the doghouse in the opening, gets rid of it. Peppermint Patty is introduced taking over the baseball team. Linus evades his blanket-hating grandmother by mailing his blanket to himself, and it goes wrong.
