Franking signature, “Free, John Adams,” on a 5 x 3.5 mailing panel affixed to a same-sized card, addressed in hand to his son, John Quincy Adams, in Philadelphia. In very good condition, with mounting as noted, scattered light staining, and a few faint folds (lightly touching “A” of signature and top edge of recipient’s name). An unusual and significant association! Auction LOA John Reznikoff/PSA/DNA and R&R COA.
