I am not sure whether this paperweight was something given out to employees or customers. Maybe the decorated the lobby with them. I am not sure who collects vintage bank memorabilia but if your out there this is for you. I am guessing it is from the late 50's to 60's based on the wear on the bottom and this statement:
From 1953 on, the new name was Genossenschaftliche Zentralbank Aktiengesellschaft, with the abbreviation GZB also being used for the company.......... in 1989 it was renamed RZB Raiffeisen Zentralbank Österreich AG
Measures 2.7 inches across ( 70mm ) Aside from the scratched bottom it is in good shape.
