I'm having trouble finding this note in any catalog. The only information I have is that it's 1 Kopek from the city of Libau in Latvia from 1915. Both sides of the note are identical. Is anyone familiar with these?
Quote: Libau was ... occupied by the German Army, on 7 May 1915, and in memory of this event, a monument was constructed ... in 1916. Libau's local government issued its own money for a while in this period - Libaua rubles.
