Q. I am researching an opal glass beaker in the British Museum collection which may have come from the von Lanna sale in Prague 1911 of which you have the catalogue. Could I see copies of the entries in that catalogue as it might refer to this piece?

Our library has an old photocopy of the glass-related pages of the Rudolph Lepke Kunst-Auctions-Haus sale no. 1605, collection of Adalbert von Lanna, Prague, 1911, and we will be happy to provide you with a copy in support of your research.
