Charlie Brown's Books of Questions and Answers

I don't know if I am the only one remembering them, but back in the days, like inthe early 80s, there was a series of books, called "Charlie Brown's Great Books of Questions and Answers" It featured the Peanuts gangs in their usual comic strips, of course, but with lots of educational articles about thigns: means of transports, biology, traditions, etc. We had the book on transports, I remember one of my friends had a few of them, including the fourth one, about customs and traditions in various cultures around the world. It is the one I liked the mos and I spent a lot of time reading it when I was visiting him (I know, I was a lousy, socially inept friend). He thought little of it, but then again he was not as much of a reader as I am. Anyway, I found it online, second-handed, at a decent price, so I decided to buy it for my son, because I think it is quite educational. Yes, that's the excuse. I have another reason which I will explain in another post, when I receive it. But going through this will taking another pleasant trip through memory lane.
