The Complete Peanuts Vol 16

In Snoopy-family news, Spike is drafted into the Infantry (don't worry, it's only Snoopy's imaginary World War I army), and a brand new brother, "Marbles" (with the spotty ears) takes his bow. We also see two major baseball-oriented stories, one in which Charlie Brown joins Peppermint Patty's team, and another in which Charlie Brown and his team lose their baseball field.
