Important German composer (1813–1883) who single-handedly revolutionized opera and attained status as one of the most influential geniuses in the history of music. Enormous matte-finish 17.5 x 25 photo of an engraved portrait of Wagner, prominently signed and inscribed in German in the lower border in black ink to Carl Bertileni, and dated Tribschen, September 24, 1871. Silvering to dark areas of the image, light scattered surface marks, and some trivial chipping to corners and edges, otherwise fine condition. Tribschen was Wagner’s home in Switzerland from 1866 to 1872, where he finished composing his acclaimed three-act opera Die Meistersinger von Nürnberg. Rare in signed photos, this is just the sixth Wagner we have offered—and the previous examples consisted of four cartes-de-visite and one cabinet card. The imposing size and large signature easily make this one of the finest pieces we have encountered from any genre. Pre-certified John Reznikoff/PSA/DNA and RR Auction COA.
