Pair of Kinderausweis - 1937 child ID’s, Berlin siblings

Two Kinderausweis (children’s ID cards issued to minors under the age of 15) issued on June 29th 1937 to two children residing in Berlin. One is issued to Udo Fürstenau (born October 1928) and his sister Flora Fürstenau (unsure of her first name, born May 1925). They appeared to reside in the Kreuzberg district of Berlin judging by the address written on the cards. Each card has the appropriate certification stamps by the Berlin authorities, as well as a passport photo of the child in question. The ID’s could be used to travel within Germany, as well as to Austria (which hadn’t been annexed yet). Both are in very good condition. These particular Third Reich ID’s don’t come up very often. Nice to see the pair for children from the same family, which is even less common.
