used LK (double letter K), with pen ink cross, just clipped at foot of L square, margins otherwise all round; small faults and slight discolouration on reverse, possible evidencing attempts at official removal of the ink cross, but otherwise fine. R.P.S. Certificate (1988). Also an 1840 1d. with the upper squares showing faked "V" and "R". Photo for the first
