If you don't already have the third volume and/or you're looking for an ideal gift for the Peanuts fan, this deluxe slip-covered box set is a terrific value.  It contains a copy of both Volume Three and Volume Four (these are the exact same editions as of those copies sold indivdually) of The Fantagraphics Books edition of the Complete Collected Peanuts, collecting every daily and Sunday strip from the years 1955 through 1958 -- 1,461 strips in all.   The spiffy -- and heavy duty -- slipcase is a perfect fit and is designed for years of use by series designer, Seth.  All this for significantly less than just the two volumes by themselves.  A great value, and now in stock!
