ALS in French, three pages on two adjoining sheets, 5.25 x 8.25, December 25, 1902. Letter to influential art critic and author Gustave Geffroy, in which he thanks Geffroy for his letter and apologizes for missing him when he was recently in Paris. Monet discusses family matters, thanks Geffroy for sending him his book Le Louvre, and mentions that he never received a copy of his previous book Belleville. In a postscript, Monet asks Geffroy to wish the painter Carriere well and to send his regards for a speedy recovery. In fine condition. Accompanied by the seldom encountered original mailing envelope, addressed in Monet's own hand. Geffroy was a founding member of the literary organization Academie Goncourt in 1900 and is noted as one of the earliest historians of the Impressionist movement. He championed Monet after meeting him in Belle-Ile-en-Mer in 1886, where Monet busied himself painting the local oceanside rock formations, works which astounded the Paris art world when first exhibited in 1887.
