5c blue, 1862, vertical pair, fair to large margins on three sides, touching at left, tied to cover by "Gordonsville / VA / Aug 28 / 1862" c.d.s., to Hanover Court House, Virginia, endorsed "R.E. Lee / Genl" at upper right, some trivial creasing and adhesive-mounted to black card, fine and rare; with 2023 Civil War Philatelic Society certificate.  
General Lee's field correspondence was typically carried via military courrier; examples sent through the postal system and bearing general issues of the Confederate States are particularly scarce.
