This is a list (work in progress) of Enid Blyton books (and vinyl) showing boys or girls in (mainly long) bibs on the book cover. Most have illustrations inside but these could not include bibs and depending on the illustrator and depending of the country and of the editions. First I had problems finding the English title as some are not included in the list on German Wikipedia. Most of the German editions are from the 70s. Only few have been made into movies. I can't check every cover of every editions and every country. There are 700 English books. Makes thousands of different covers.
