Norwegian Enamel

The brooch depicting a lake scene with swans in the foreground is made by Gustav Gaudernack (1865-1914) of Norway. It is in perfect condition otherwise needs to be cleaned. ( I did not want to damage it in any way by attempting to clean it). backstamp reads: G.G. 925S N.M. The pin is secure but not visible in photo because in order to show the stamp I laid the pin open.
