This is an original letter written by Prinz Heinrich of Prussia (1862-1929). Heinrich was the younger brother of Kaiser Wilhelm II. Heinrich served as the head of the Kaiserliche Marine in the rank of Großadmiral. He served in that capacity until he disagreed with Großadmiral Alfred von Tirpitz. Heinrich lost out on that power play when his older brother backed von Tirpitz. Interestingly, this handwritten letter is on an 8 3/4″ x 5 3/4″ piece of paper that has been folded in half and bears the embossed seal of the Kronprinzessin Cecilie. She was his niece by marriage, a princess from Mecklenburg-Schwerin, and the wife of his nephew, Kronprinz Wilhelm, the heir to the Hohenzollern throne and the man who never became Kaiser after the monarchy fell in 1918. This letter was written 22 April 1922 in black ink. A partial description of the letter in German is included.
