A print of the only photograph taken of legendary composer WOLFGANG AMADEUS MOZART's widow has been discovered in the archives of a German town. The long-lost image of CONSTANZE WEBER was taken in 1840 at the home of the composer MAX KELLER when she was 78 years old. And the state archive in Altoettingen is adamant it was the only time she posed for a photo. Weber was 29 years old when Mozart passed away in 1791. She went on to wed Danish diplomat GEORG NISSEN and died in 1842.
