A fine and scarce lettersheet franked with four 1841 1d Reds from Plate 81 lettered PJ. QI-QJ and RI. QI just touched NE otherwise all very fresh 4 margin with typical blurry letters and superb 717 numerals of Slough. used to Marlborough 27 June 1850. Filing creases barely detract and do not effect stamps. Attractive and very scarce.
