A very interesting and rare medal commemorating the 25th anniversary of their marriage on May 13, 1885.
Modeled on the Minheymer medal minted for the 25th anniversary of the marriage of Simon Rosen and Henrietta Epstein (pieces from the E.Hutten-Czapski collection available in the digital collection of the MNK).
Signed K-B, most likely by the Warsaw medalist Bartoszewicz Kazimierz (another engraver working during this period is also known: Blaszkiewicz Kazimierz, but the style of the work is more suited to Bartoszewicz).
Bronze, diameter 29 mm, weight 19.0 g.
