The other 6 books do not have cover jackets. Dinosaurs and animals only come with DVDs. Stars and Constellations comes with a star chart. There is some yellowing and fading due to age. There are also folds and damage to the corners of the covers. The contents are mostly in good condition, and from a quick look, there doesn't seem to be any writing, but there may be minor stains, folds, or tears. Please check the photos and purchase accordingly.
