Remember these great books from your childhood? I couldn’t believe it when I stumbled upon this complete set, even including the index! This listing is for a COMPLETE SET of the classic “I Want to Know About. . . .” Series. You will receive 17 books plus the index for a total of 18 awesome books. Each hardcover book is filled with super cool, retro, color and black & white illustrations. These educational books were created with a 5 to 10 year old audience in mind and were based upon the “True Book” series which was published by Children’s Press of Chicago in the mid 1950’s through the early 1970’s. Written by several different authors, each book contains three separate mini-booklets on a variety of subjects. Books have roughly 48 pages and measure 7½ by 5/8 by 8½ inches each. Overall condition is good to very good. Someone took good care of this collection over the years! All binding, covers, and pages are intact with no tears or markings but some yellowing due to age. Paper is thick and of good quality. Books do have some minor shelf wear around the spine, edges, and corners and there is also brown spotting on the covers, spines, and along the top of the pages.
