Ahhh – who doesn't love a stack of cheap and cheerful vintage children's books? Do you know how many books there were in this classic series of the 1950s and 60s? And which ones have multiple covers, multiple illustrators, and even in one case two different authors? This video includes an interesting history (well, I think it's interesting, but then I'm certifiably book crazy), as well as all the covers and even a selection of illustrations from *every book* in the series.
