Really nice hard cover copy of this children's encyclopedia. Was a school library book but looks lightly used. 

Quite clean inside with some minor, normal use flaws. Nice, solid binding.

Covers many children's subjects with illustrations. Just a neat piece of our young people's school history.

We have other books listed including the 1953 copy of the book of knowledge.  

Take a look at those if you're interested. We're happy to combine purchases to save on shipping costs for buyers.

Thanks for looking!
