10c Green, E. Grill (89).
Original gum, lightly hinged, deep rich color, clearly-defined grill, wide

While blocks of the 10c F Grill have been broken in recent years, yielding some choice single stamps, the 10c E Grill blocks are extremely rare and always have been. Caspary's block of 18 was broken years ago, but many of the stamps had faults or disturbed gum. Few other blocks have become available to furnish singles. This stamp is certainly among the finest extant.
