Diorama af den Nordiske industri-, landbrugs og kunstudstillung i Kjobenhavn

The folding diorama (or teleorama), which was popular in the nineteenth century, was also produced as a souvenir. This specimen commemorates the Nordic exhibition of Industry, Agriculture, and Art of 1888, which was held in Copenhagen. If you pulled the teleorama open, you could look through a peep-hole at a series of images like stage scenery that are connected by paper strips. The result is a three-dimensional image, a transportable perspectival theatre that recreates the experience of visiting the exhibition.
