cover 1840 1d. plate IX, BG-BH pair (margins virtually all round, BG just touched at foot) on entire letter to Preston dated 19 May 1841, lightly tied by faint black Maltese Cross and the pair showing central complete strike of the black "Poulton/Penny Post"; the cover with minor faults and faint enclosure bend crosses the adhesives but does not detract. Attractive and rare. Photo
