Quite an historic photo.  This original photograph (not print) depicts Reinhard Heydrich at his desk surrounded by 4 other SS officers, all members of his staff.  An excellent study of cuff title wear (you can see an SD-Hauptamt title, a generic SD title, and two staff bands.  The Standardtenführer in the front is wearing a Totenkopf Ring (you can barely see it).   Please note: The German Cross in Gold is photographed for size comparison, and not included.
