However, it's worth checking out the new Fantagraphics The Complete Peanuts. The first four volumes (through 1958) are available.
Think about it.
Peanuts when the jokes were new. Peanuts when Schultz was still taking chances.
Peanuts when Snoopy was pretty much an ordinary dog, not Walter Mitty with a bulbous nose.
Charles Schultz was never a hack, even if he did fall back on formula after a few decades of doing his strip. Most syndicated comic artists fall back on formula much sooner (Jim Davis, anyone?).
But newspapers aren't running these strips, they're running 1970's reruns. I suppose they think starting over from the beginning would confuse too many people (and it probably would; many cast members are unfamiliar to current readers).
They're brilliant, though.
There's much more pre-school to these wise-beyond-their-years pre-schoolers. Snoopy is an ordinary dog, no thought balloons, and has a much more beagle-shaped nose.
I know you're not going to believe what follows, though.
Not all of them, but many of them. Early Peanuts was much more subtle in its philosophical bent. That's not to say the jokes were more subtle. Early Peanuts was very absurd.
Most interesting, though, is watching the introduction of new characters, often very different from their current incarnations. Schroeder playing the piano before he could talk. Lucy, fuss-budget of the year, in footy pajamas and eating in a high-chair. Linus without a blanket. And, of course, Snoopy as an ordinary dog.
Can you tell I like the early Snoopy?
There are also the failures. Charlotte Braun, the frizzy-haired loudmouth (and visual model for the later and longer-lasting "Frida") didn't last a year, and for good reason.
I also love the characters that lasted, but eventually still disappeared. Patty (not "Pepperment Patty"), Shermy and Violet were early central characters who have faded into supporting roles or even disappeared. For years Patty and Violet's mud pies were a staple joke, but Patty isn't even present in later strips.
So the simple answer?
Buy it. At least the first two volumes.
Read it. At least the first two volumes.
