Wagner, Richard - Signed Cabinet Photo

Beautiful cabinet photo signed by the famous German composer (1813-1883), most probably inscribed to notable German music scholar Ludwig Nohl (1831-1885). Wagner writes "respectfully yours" under Nohl´s name, and boldly signs at the bottom. 

A cabinet photo by Elliott & Fry, London, size is 4.25 x 6.5 inches, in excellent condition - see scans of both front and verso.
