Three items: a TLS signed “Mark W. Clark,” one page, The Citadel letterhead, February 29, 1968, sent to Robert L. James, in part: “I have autographed the First Day United Nations Cover as you have requested and it is returned herewith”; the referenced UN FDC, signed in blue ballpoint by Clark; and another FDC with a UN Observers cachet signed in blue ink by Matthew Ridgway, “M. B. Ridgway, General US Army, Retired.” In overall fine condition.
