Katalog über optische, mechanische und elektrische Spielwaren und Lehrmittel: Metall-Miniaturen, Metall-Bauksten 'E.P. Modello', Nähmaschinen
A 1925 trade catalogue from the Nuremberg toy maker Ernst Plank, listing optical, mechanical and electrical toys and teaching aids — magic lanterns, model steam engines, metal construction sets and toy sewing machines — for dealers and buyers. Each item appears as a small numbered engraving in dense hatching: sawmills, boilers with flywheels, lantern projectors, perforated-strip machines, isolated on white with cast shadows.
