<p>1930-31 12c grey-black, upper right corner IMPERFORATE BLOCK OF FOUR with 'PLATE NO. 1', mint o.g. (actually unmounted, but the gum a little toned with slight disturbance from storage). Very fine fresh appearance and a great rarity. Only 75 imperforate pairs existed (= three panes of 50), making the one of only three possible plate blocks, and unique from this position.
