Mention Ladybird books to anyone who grew up during the Baby Boomer years or the Swinging Sixties and a warm glow of nostalgia invariably washes over them. With detailed colour illustrations, each facing a page of text, these slim pocket-money volumes touched the lives of children across Britain.
The golden years of Ladybird books began in the 1940s and lasted until 1972, when the company changed hands at the height of its success. Popularity gradually waned, the UK printing operation closed, and today Ladybird is part of Penguin Random House with formats that target a new generation. But when it comes to the vintage titles, few people know more about the books, writers and artists, and the changing world they represented, than ex-English teacher Helen Day.
