Lot contains 23 "Zoobooks" and 18 "Zoobooks2". Condition varies between books but all show some varying degree of wear. Most of the wear is in the covers / spines. I flipped through a handful of them and didn't see any scribbles or writing inside but it's possible that some do.  The years range from 1980 to 1991. The most common years I saw were 82, 83, 87, 88.

Issues / flaws:

Three of the Zoobooks - Birds of Prey, Snakes and Apes, have separated, i.e. front / back pages are loose - shown in the last pictures.

The Camels Zoobook has pen drawn on the front.

Several books have folded / creased pages.

All books have a mailing label sticker attached to the back.
