From documentation to experience: functional expansion of exhibition catalogues: Concrete in Sight deals with alternative formats for exhibition catalogues. It focuses on the context of the exhibition venue and shows how the medium can enrich the exhibition experience by expanding its design and content. The bilingual preliminary catalogue is an extension of the Boros Collection exhibition catalogue in the Boros Bunker in terms of design and content. It guides visitors along the imposing outer wall of the bunker, provides information on the surroundings, history and architecture and thus makes a fundamental contribution to an informed and exciting exhibition experience.
