Autograph letter signed.

1 page. 4to. With autograph envelope. In Yiddish, to Haim Gamzou (1910-82), director of the Art Museum in Tel Aviv, concerning his works for the state hall of the Knesset building and for the Metropolitan Opera in New York: "Liber Gamzu: A dank farn brif. Ich bin gekumen fun Amerike aher wo ich hob em bakumen. Ich hob gemeint az ir hot efscher a bisl fargesn Chagall [.]". Chagall expresses his sorrow about having been unable to attend the opening of the Knesset because he was tied up with finishing three tapestries ("Gobelins") that he wants to donate to the Knesset. Meanwhile, he has been to America, where he surveyed the installation of his tapestries at the New Metropolitan Opera. Unfortunately Chagall has to visit America a second time in January to work on Mozart's Magic Flute. - Chagall created two big wall paintings, located in the entrance hall, for the opening of a new building of the "Met" on 16 September 1966. For the Knesset Chagall designed, next to floor mosaics, as well three large tapestries that were unveiled on 18 June 1969. - Slightly creased; small hole outside the text area.
