BARTHOLDI, Frederic Auguste (1834-1904). Autograph letter signed ("Bartholdi"), in French, to Albert Bierstadt. New York, 6 November 1886. 1 page, 8vo, creased at folds, on Hoffman House, New York stationery. Following a visit to the Statue of Liberty, Bartholdi apologizes to the American artist Albert Bierstadt for missing an engagement. "Dear Mr. Bierstadt, I am returning from Bedloe Island where I had gone to study the lighting of the statue [of Liberty]. I feel tired and very exhausted, please excuse me to our friends and colleagues of the Circle. In spite of the strong desire I have to come and see you, I am obliged to put this pleasure off until another Saturday. Your very devoted Bartholdi."
