Since the first days of 1796, Letts has been manufacturing in Great Britan and proudly passing the bookmaking knowledge and skills from one generation to the next. When John Letts combined a journal with a calendar in 1812 he engineered a unique accessory, inventing and publishing the world’s first known commercial diary. Letts offers a wide range of calendars in different designs and sizes - available in both school and year-round calendars. Letts of London - the original - stands for genuine feeling and quality.
