MARGARET MATZENAUER. Vintage 8×10 matte finish silver tone chest-up portrait, boldly signed with her name alone in black fountain pen. Fine condition, with light toning in the left border; a single pinhole in the top and bottom borders; and a small bend to the top right corner tip. The impressive Golden Age mezzo-soprano enjoyed a lengthy international career, including 19 seasons with the Metropolitan opera, excelling in the major roles of the Italian and German repertory and leaving behind a rich legacy of recordings.
