I used to wonder about that "Part 1" and "Part 2" business, until I saw some of the other books. I got a few of them-- somehow-- but for whatever reason, they never seemed to turn up much. Maybe they were distributed to different stores? (It's possible.) It's just strikes me as funny that the big ones were a buck, and the Fawcetts were 50 cents each. So... SAME price. But, I suppose it's easier to buy the Fawcetts if all you have is 50 cents.
So it wasn't just the line reproduction quality (better stats?), but also the paper as well? Maybe 50 cents wasn't the bargain it seemed...?
The Fawcett book with that "Comic Magazines" strip-- red cover, as I recall-- somehow went missing when I was loking for it awhile back. I had a few of the early ones, but the earliest I had were actually reprinted in a "Book of the Month Club" anthology. That's a thick hardbound book with like 4 novels and some other stuff all in a single package. And they included PEANUTS sometimes. Crazy. It was ne of those I got to really like the early stuff, I think, before I even got the "early" paperbacks.
More recently, someone began a "COMPLETE PEANUTS" reprint series, all in hardcover, one strip per page (I think). More than I could afford, but I did get the 1st book because it seemed a good idea. They said their intention was to feature EVERY strip in sequence, and some, apparently, had not been included in previous reprints (for whatever reason).
It was a blast reading the series right from the beginning, and seeing the characters introduced one by one and slowly start to develop.
