This is the kind of question that the "Stump the Bookseller" page at
www.loganberrybooks.com is designed for. Search their database of already-answered questions and if you don't find the answer, send in your question. They've developed a community of people including current and retired librarians who are very familiar with childrens' books.
It would also help to know how many years ago you read this book, and if it was new or old then.
