Great Britain 1841 1d Red brown Plate 137, SG8.
Very fine and fresh unused, with original gum, four margin block of nine lettered AF-CH. There are a couple of light creases as normally seen, which are not visible on the surface and do not affect in any way the wonderful appearance of this block.
The deep colour and strong ivory head give an unusual cameo like appearance to the Queen's portrait.
A most unusual and beautiful Queen Victorian philatelic rarity.
