Legendary pop group ABBA have released a special book to mark four decades since they released their album Waterloo.
The hardback book is called ABBA: The Treasures and includes previously unseen photographs, as well as personal removable memorabilia such as facsimilies of written set lists, tour itineraries and hand-annotated sheet music.
The book has been compiled and written by Ingmarie Halling and Carl Magnus Palm, with a foreword contributed to by all four members of the group.
Halling travelled with ABBA on all of their major tours and was responsible for the dressing room, costumes and make-up. She is currently the curator of the ABBA museum in Stockholm.
Palm has written a number of books on ABBA over the past two decades and has revealed previously unpublished interview material in this latest book.
