GB QEII 1969 Concorde: 4d SG784var :2×1.5mm bands. Unusual variety, I have not seen this variety anywhere before, possible numbers produced/available may be limited to only one sheet , or possibly only one vertical strip on the sheet. So there will be very few in existence as it is a printing error when the phosphor bands were applied. Also noticed a 1.5mm shift in the blue at the top of the stamp noticeable on the left hand frame of the printing. 2 errors in one!
