The Illustrated popular Encyclopedia Library Space Science Vol. 1 & 2 by Harold Joseph Highland 1963 HC Book Set by Bobley Pub Corp

popular Who doesn't love books on space science written during the space race / age? These intensive books are filled with useful knowledge accompanied by illustrations and charts. Each book is in great shape. The pages are clean, bright and crisp and free from tears, creases or unwanted marks. However the covers do have light appropriate age and wear, and the spines are discolored from sun exposure. Lastly Volume 1 has wrinkles on the cover, as though the adhesive lifted in places. This is not that noticeable.
