Spanish operatic tenor (1869–1919) who, in the course of his international career, earned a reputation as one of the most “difficult” performers of his day. Vintage matte-finish 4.25 x 6.75 photo of the singer in character, appropriately enough, as Constantino in Tosca, signed and inscribed in ink, “To Mr. Harold Whitney, Souvenir of F. Constantino, 1910 Boston.” A few very faint marginal bends and a hint of subtle silvering to dark portions, otherwise fine condition. R&R COA.
