Description: Stained glass Standesscheibe of Unterwalden (1564)(more accurately, of Nidwalden, presumably the right half of a Standesscheibe showing both Obwalden and Nidwalden. Nidwalden had used the double-key as the design of its war flag from the early 15th century. The red-and-white design formerly representing Unterwalden as a whole was now used by Obwalden). Kept in Sułkowski castle in Bielsko-Biała (Poland).
