With books, value is all about Rarity, Author, Edition and Condition, with signed first editions by famous authors in very good condition being the most sought after. Books should be kept out of direct sunlight and stored in dry conditions. Damp conditions with quickly cause books to develop mildew and mold causing discoloration and rot. Sadly then there was not much interest by the average person in this book and no blockbuster movie deals either, so values tend to be very modest even for First Editions in very good condition. This one is not a first edition, later printings like this in “fair” to “good” condition nearly always sell for under $20.00.
