My Grandma bought the first one for me as a Christmas gift long, long ago. I believe it was the first time I had ever seen a comic book with naughty bits. Primordial salamander creatures getting it on, barebreasted cavewomen running amock... it was all quite scandalous to my tiny little mind.

But yeah, these are great books. I can enjoy them now just as I did back then. Humorous, well drawn, efficient little primers on world history. A great tool for getting youngsters interested in the subject. Although these days, they probably have X-Box games and crap for all that.
