Address Labels and Envelope Seal for Correspondence from Adolf Hitler.
The seal goes on the envelope flap. It says "Der Führer und Reichskanzler" and features the Reichsadler. 
The address label (can be filled out on the period typewriter like originals were) goes on the back on the envelope. It states the name, optionally the profession and address of the recipient of the precious letter. 
The set is good for all documents signed by Adolf Hitler, e.g.
German Mother's Cross certificate,
50years Wedding Anniversary Diploma,
SS Long Service Award Certificate,
Blood Order Certificate,
Coburg Badge Certificate,
NSDAP Long Service Award Certificate,
Christmas Card, or Letter from Adolf Hitler,
or Retirement Congratulatory Letter (fantasy item)
