Two items: a Vice President's Chambers card, 4 x 2.25, signed in ink by Calvin Coolidge; and a White House card, 4.25 x 2.75, signed in ink by First Lady Grace Coolidge. Also includes an off-white 3.25 x 2.25 card signed by Coolidge's vice president, Charles G. Dawes. In overall fine condition, with light stains to the two Coolidge cards. Accompanied by a letter of transmittal from Washington politician Cal Anderson, who graciously forwarded these signatures to the collector; also accompanied by a laminated four-leaf clover, a unique hallmark the original collector offered in trade for autographs.
