This Abraham Lincoln Signature appears to have been clipped from an autograph album.
Framed with a cdv or contemporary engraving, this would be an outstanding presentation.
Excellent, bold, and carefully written; mat-burn around the edges is easily matted out.
Lincoln, Abraham. Autograph Salutation and Signature “Yours Truly / A. Lincoln.” No place; no date, though probably presidential, clipped from a war-time autograph album.
