For sale is a set of 20 books from the illustrated and encyclopedia of the animal Kingdom. There are also three other animal books of the same era. The books are from the 1970s with the other three books from 1973 to 1976. These books have been in my family for many years. I am now moving and unable to bring them with me. The books in condition from good to excellent. The price is $200 but I would be willing to discuss a lower price with a reasonable offer.
