In a Big Store, Ladybird Easy Reading Book

The classic pocket-sized mini-hardback Ladybird book measured roughly four-and-a-half by seven inches (11.5 cm by 18 cm). Early books used a standard 56-page format, chosen because a complete book could be printed on one large standard sheet of paper, a quad crown, 40 inches by 30 inches, which was then folded and cut to size without any waste. It was an economical way of producing books, enabling the books to be retailed at a low price which, for almost thirty years, remained at two shillings and sixpence
