Excellent group lot of four ink signatures of noted American authors on off-white cards ranging in size from 3.5 x 2 to 5 x 3, including: Oliver Wendell Holmes, who adds “Boston, Jan. 20th, 1875”; James Whitcomb Riley, who adds the quote “The golden olden glory of the days gone by” and the date, “July 3d 1907”; Carl Sandburg; and Upon Sinclair. In overall very good to fine condition, with a few occasional stains.
