Highly regarded and influential Mexican artist (1886–1957) who earned international acclaim—and stirred up much controversy—for his powerful, politically charged murals. TLS, one page, 8.5 x 11, December 29, 1940. Rivera writes from San Francisco to Quinby Self. In full: “I am sorry to have been so late in answering your letter, but I have been rather undecided as to my plans. I am sorry I was not able to be in Mexico during the hollidays [sic] so that I might have been able to meet your wife and see her paintings, but I am just now able to start toward the south.” In good condition, with toning, large paper loss along one fold (not affecting any text) and a few small holes (one near signature), the signature nonetheless strong and clear.
