This is an ORIGINAL letter signed by King Friedrich Wilhelm IV (1795-1861). Friedrich Wilhelm IV was King of Prussia (1840-1850). He was removed from the throne after he went insane. The letter was written in the castle at Charlottenburg on 30 December 1847. This dealt with the promotion of a young Portopeefähnrich to Second Lieutenant. The officer in question was Graf zu Stolberg Wernigerode. This action was taken by Friedrich Wilhelm IV as the head of the Gardekorps. The young officer was attached to 1. Garde-Regiment zu Füsilier. It is a fine early promotion patent to a young nobleman. The format is different from what was used by both Kaiser Wilhelm I and II.
