The Ed. Liesegang firm, founded in 1854, became one of the largest companies in the photography field in Germany circa 1880. Among its products were series of magic lantern slides — a collection of images organised primarily according to market demand, but that nonetheless presents an overall structural logic. This collection, however, no longer exists, since Liesegang did not create archives for the products that it put on the market. This collection of images thus constitutes a “virtual collection” whose outlines can be reconstructed based on sales catalogues. This kind of virtual collection does enable hypotheses to be made that not only concern the demand and tastes of the clientele, but also the categorisation and hierarchies that were established between the series according to their commercial importance or the number of series dedicated to a subject.
