Last weekend I went to a local library book sale and found a Gus the Ghost book to add to my collection. I absolutely loved these books as a child and have found them to be equally loved by my kids. Gus, a very benevolent ghost, is always looking for a playmate and some adventure. And adventures he has! The books were written by Jane Thayer and illustrated by Seymour Fleishman. Gus Was a Friendly Ghost was the first of many Gus books — the series ran from 1962 to 1989. Any fans of these books on the page?
