<p>The display case has a housing (19), with at least one transparent panel behind which an exchangeable poster (2) can be arranged. It also has equipment (1) for exposing the poster to permanent tension forces, when in the housing. The equipment has one or more sources (6) which can exert compressive and / or tension forces, and which can be converted into tension forces by connecting elements (4). The poster can be connected to the equipment by holders (5), and the forces act on all of these, or on individual holders. The latter may also be arranged so as to hold the poster in its edge regions, and especially in its corner regions.</p> |
