This is an encyclopedia from almost 50 years ago. In addition to volumes 1-33, there is an encyclopedia and map summarizing the events of 1978, but due to shipping constraints, it is being sold in two boxes (①②). This box contains volumes 1-17. 29 x 21 x 3 cm As you can see in the photo of volume 12, there is some scuffing on the spine, but the contents are very clean.
