This 1956 edition is both informative and entertaining. The boards are strong, and binding is in good condition too. I find no tears, marks or missing pages in this used publication. There is foxing in places, and the sale includes a semi-stained, and tattered dust jacket that has served its purpose in protecting this publication well. Profuse illustrations, diagrams and B/W photographs. Media rate. I sell internationally, so message me for a quote to your country.
