The 1923 Jubilee Exhibition in Gothenburg was an impressive manifestation of Gothenburg's role and importance as a centre of national and international trade, technology and culture. Despite the historical perspective, the focus was primarily on the present and the future - all in a spirit of optimism and confidence. The exhibition was also characterised by its thoughtful and ambitious communication. Using modern graphics, typography, photography and film, the exhibition messages were distributed through albums, postcards, posters, brochures and other printed matter. As Gothenburg wanted to be part of a worldwide context, the focus was also on the international audience. This aspect of the extensive project, which took place exactly 100 years ago on the site where UB and HUM are located today, is the focus of the GPS400 exhibition Here and Now - There and Then: The modern visualisation of the jubilee exhibition around Näckrosdammen 1923. In displays and on screens, a concentrated picture is presented of how text and image collaborated in order to spread knowledge of Gothenburg's history, present and future dreams.
