Helsingborg Exhibition 1955, or H55 as it is sometimes known was a BIE (Bureau of International Expositions) recognised world's fair held in the town of the same name, in southern Sweden.
The theme of H55 was primarily arts and crafts, curated with the aim of showing the many ways in which modern design could be integrated into commercial items and luxury goods. The fair drew exhibitors from over ten countries (no mean feat at the time) and included the String Bookshelf by Nisse Strinning.
While H55 was the last world's fair to be held in Sweden, it was not the first exhibition of its kind to visit Swedish shores. Indeed, there have been six in total stretching back to the General Art and Industrial Exposition of Stockholm in 1897, there was even a dedicated Aviation exhibition in 1936 and one focusing on sports in 1949.
