6p Chestnut, Overprinted “OS” (BW 23(OS)).
Remarkable complete sheet of 120 from Plate 3 (upper), consisting of the left and right panes of 60 separated by a vertical gutter and with scarce John Ash imprint at bottom (BW 23(OS)z),
“N” over “N”, Mint N.H., exceptionally well-centered as an entire sheet, strong fresh color, few separated perforations mostly in bottom selvage, plus a few really trivial tone spots on just a few small areas, Very Fine overall, there is no doubt that few intact sheets such as this remain, catalogued simply as a hinged imprint block of four and 116 Mint N.H. singles
