Part of a large collection of opera ephemera I recently acquired. All signed items are absolutely guaranteed genuine authentic hand signed by the artist indicated. This particular autograph is quite hard to find, from the estate of an advanced opera collector, I can provide provenance and will guarantee forever it is genuine. 

Giulio Gatti-Casazza (3 February 1869 – 2 September 1940) was an Italian opera manager. He was general manager of La Scala in Milan, Italy, from 1898 to 1908 and later the Metropolitan Opera in New York City from 1908 to 1935.
