Dritter Band.
This is a bookplate-style label from the Eisen-Bibliothek, an iron-and-steel industry library founded by the Georg Fischer Aktiengesellschaft in Schaffhausen, Switzerland, and this picture shows only its ex libris label rather than the book's contents. The label carries a red wax seal of a standing armoured figure within a pointed oval, under the Latin motto 'Viris ferrum donantibus', so a designer might borrow the seal-and-motto layout for heraldic or corporate-heritage identity work.
