1 page, 5.5 x 8.5 inches, Monrovia, California, March 14, 1962. In this charming letter, Sinclair accepts an invitation to a ball, in part: "...I am coming to NY ahead of that. So I can attend your Ball on Apr 27 if you like. But I can't dance. My wife, who is only 79, will do it for me..." Two vertical folds and a paperclip impression at top of the page; very good condition.
