Miss Nelson is Missing by Harry Allard. 1977.

Clever story line, simple and fresh illustrations. I expect parents took issue with a story about naughty children and a teacher who is called a witch back in the day. It’s standard fare now, though. I mean I have Heckedy Peg on my bookshelf, along with books about farting dogs and dumb bunnies. Interesting write-up about this book and its origin in Anita Silvey’s 100 Best Books for Children. Far too lazy today to comment more. Fun book and Pie, Fish and I loved the CD/book combo in this particular release.
