The German Empire had a colony in todays Cameroon. Issued three different notes. Should it either have a ruler of their own, or a their own sub-section under Cameroon?
Remember to link it to the former German colonial empire :)
If it gets their own issuere, the ruler should be Wilhelm II, from the House of Hohenzollern.
Edit: Should also have Mark as its currency, with denominations of 5, 50 and 100 Marks. Not sure about the time range though.
