These books are great to decorate your home library or showroom. This set of 15 books are called Bonniers Konversations Lexikon by Albert Bonniers Forlag. This amazing set of dictionaries has several words per page that are accented with a black and white picture. Each volume has a different copyright date ranging from 1935 to 1939. I believe these books are written in Swedish for they say Stockholm. Volumes 3, 4, 14, and 15 are missing with duplicates of volumes 7, 11 and 13 for a total of 15 volumes. The binding of these books are light brown and accented with black pin stripes. The front and back cover are marbled with light brown, dark brown and tan. These books are in excellent condition.
