Theater-related sheets represent one of many different types of picture sheets that were widespread in the 19th century. With their help, the theater-loving bourgeoisie could enjoy popular plays or operas at home and actively reproduce them themselves. Characters and decorations from the paper theater were printed as picture sheets that served as cut-out templates. The sheets provided everything needed to build a stage: stage fronts ("prosceniums"), curtains, backdrops, side wings, soffits, set pieces, and characters.

Among the purchased paper theater sheets are eleven from a little-known and extremely rare series, the "Kleine Schaubühne von Jos. Scholz" (Small Stage by Jos. Scholz), which can be dated to around 1860. A small proscenium on a sheet measuring approximately 33 x 43 cm even contains the figures for a theater orchestra. What is special about the decoration sheets is that each sheet contains all the backgrounds, side scenery, and figures needed for a particular play (or even just a specific scene from a play). In paper theater, it was otherwise customary to have one sheet as a background and at least one sheet with side scenery and other stage equipment, as well as a sheet of figures. The background and side scenery usually depicted settings that were common to several plays (such as a forest, castle, farmhouse, or harbor), but several different ones were usually needed for a single play. In order to be able to perform a play in a "normal" paper theater, at least five additional sheets were required in addition to the proscenium and curtain, whereas only one was needed for the "Kleine Schaubühne."

Related to paper theater sheets are cut-out sheets and model building sheets. Both were also an important part of Jos. Scholz's publishing range. Cut-out sheets usually contain several figures or objects on a specific theme, e.g., farm, children's games, or fairy tales, for cutting out and setting up. Model building sheets, on the other hand, can be used to recreate buildings out of paper.
