Katalog über Zithern / Catalogue of cithers / Catalogue de cithares / Catalogo de citaras (s.l. s.n.)
Some sort of an order catalog of a company
Contains loose leaflet advertising a "Hackbrett" instrument (Cimbalom, hammered dulcimer) , made or sold by "Scala" Musikinstrumente in Klingenthal, Germany. This might let us presume the catalogue might belong to the Zupfinstrumentenfaktur C. Robert Hopf, founded in Klingenthal in 1901.
