Here are 3 lovely, very informative books from the Ladybird Books series 662 

Musical Instruments 
Ballet 
The Story of the Theatre

 All are brilliantly written and illustrated hardback books.

They were published in the early 1970s by Ladybird Books. The Story of the Theatre bears all the signs of being a 1st Edition but I'm not 100% certain. 

Between them they were written by L. Du Garde Peach, Ann Rees, and Ian Woodward and illustrated by Martin Aitchison and Robert Ayton.

All are in very good condition with light wear and rubbing to corners and edges. The Story of the Theatre has the remnants of a very old sticker mark on the rear of the front cover. Other than that, all the books are free from inscriptions or writing and the pages are all crisp, clean and fresh. 

Please check out all my photos for full details of any blemishes and a sneak peak at a few of the pages. Thanks for looking.
