Reinhard Heydrich signed letter

Reinhard Heydrich signed letter on his Chief of Security Police letterhead dated Dec.19, 1941.  Letter is a complimentary thank you to Paul Schluter for a dissertation on Jewish emancipation.  Very bold signature and the nicest Heydrich we have had in some time.  Comes with a photo card of Heydrich and an invitation from Heydrich to Schluter to a Christmas party.
