The Leiden historical student fraternity "Robert Fruin": empty bull

I used to write the names of the new members on the bulls. In return I received a free glas of Dutch gin, but that didn't make me drunk, because new members were few and far between. In the end they felt sorry for me and gave me a half bottle of gin. Now the fraternity has folded and I'm going to hand the Great Seal and the empty bulls over to the Academic Historical Museum of Leiden University.
