unused Block Larger Than four 1d. deep blue on blue, Plate 3, a complete sheet of twelve with margins all round, good colour and much original gum; the top left stamp has light bend, the third vertical row of stamps has a light crease and there are some split/reinforced perfs. Overall in a very fine state of conservation for the very few (probably only three) such sheets which have survived. An important exhibition item. Photo in colour
