This title is inspired by an exhibition entitled "The Knight is Young" held by the Royal Armouries. The exhibition features a collection of over 40 weapons and armour made for children between the 15th century and the end of the 19th century. This book is illustrated with objects from the Royal Armouries collection. The Stuart princes' armour and a set of miniature cannon made for Charles II in 1638-39 form the centrepiece of this collection.
