Set of Three Naughtiest Girl Hardback Books by Enid Blyton

This is a lovely set of three hardback books by Enid Blyton from The Naughtiest Girl series. All books were published by Dean & Son Ltd: London. The titles are as follows:
 
The Naughtiest Girl in the School 1973
The Naughtiest Girl Again 1972
The Naughtiest Girl is a Monitor 1973
 
 
Each volume is in very good condition. The boards have only light wear and the contents are all good. There is a namewritten in ink to the front free endpaper of The Naughtiest Girl in the School - the other two books are free from inscriptions. Minor spotting to the page edges but nothing significant. The Naughtiest Girl is a Monitor has the remnants of a price sticker to the front cover which is visible in the image provided.
