The Complete Peanuts 1975-1976: Volume 13 by Charles M. Schulz
As The Complete Peanuts reaches its halfway point, Snoopy's family suddenly expands, adding a brother (Spike), a sister (Belle), and even a nephew. Also in this volume, the Linus/Snoopy/Truffles love triangle, Peppermint Patty's Powder Puff Derby and obedience-school fiascos, Charlie Brown's meeting with his idol Joe Shlabotnik, Marcie's unwanted suitor, and the final fate of the talking schoolhouse building. Plus an introduction by SNL writer, 'Triumph the Insult Comic Dog' creator, and lifelong Peanuts fan Robert Smigel.
