The catalogue cover for "The Col. John Trumbull Letters and Papers" is the cover from the auction pamphlet compiled by Stan V. Henkels. Henkels used Trumbull’s “The Insignia of the Cincinnati” (noted for its importance to the Society of the Cincinnati) on the auction cover for Catalogue No. 778. The address for At the Book Auction Rooms of Thos. Birch's Sons in Philadelphia is printed on the front cover as well.
