Card mailed from Bestum, Norway to Aarau, Switzerland on December 29, 1924 . The stamp at left is in German: "The capital of Norway, called Christiania from 1624 to 1924, will henceforth be called OSLO, the name the city bore for six centuries from 1047 to 1624. The change takes effect on January 1, 1925." A big change, remembered by very few –except in Norway–100 years later.
