Steinbeck, John. Signed Document Granting Rights to David Merrick to Produce the Musical “Viva Zapata!” New York, January/June, 1963. Ten carbon pages total, partially printed document signed “John Steinbeck” twice, and signed “David Merrick” as Producer, initialed by him “DM” 25 times. Some pages originally dated January but crossed out and replaced with June. Signed by Steinbeck and Merrick on page 8, and again by Steinbeck on page 10, with two nicks to upper edge, otherwise fine. Steinbeck was awarded the Nobel Prize in Literature just months before these negotiations concluded, however the musical never materialized.
