Two items: a 6.5 x 3.5 airmail envelope addressed in Jacqueline Kennedy's hand to artist Franz Bueb, postmarked at Washington on January 18, 1960, signed on the flap as part of the return address: "Mrs. John F. Kennedy, 3307 N St NW, Washington, DC"; and a commemorative cover with a cachet honoring Dwight D. Eisenhower, signed in black felt tip, "Mamie Doud Eisenhower." In very good to fine condition, with overall creasing to the Jackie envelope.
