On 9/1/10, changed artist's nationality from "American, born Mexico" to "Mexican" to correspond to other listings for artist. (He was born in Mexico and worked in France and the United States.) Also changed spelling of name from "George De Zayas" to "George de Zayas." Birth/death dates are subject to change; his birth dates are listed variously as 1894, 1895, 1897 and 1898 and we will use the last date for now until this can be confirmed
