This immaculate phosphor cylinder block has red colour faults which in my years of collecting cylinder blocks I have never seen before. The first picture is of the block, the second shows stamp 18/1 where you will see errors in the printing of the red which has produced and extra red blob at the top and also an extra "leg" in the lower arm by the Queen.
There are other red spatters and smaller dots. The third picture of 19/1 shows an extra red blob next to the proper one at the extreme left and there is also a blue mark next to the red D in the margin.All in all a superb cylinder block for those collecting printing flaws. All listed varieties per SG Vol 3 13th current edition and phosphor varieties checked with UV lamp. This item is in the category "Stamps\Great Britain\Elizabeth II\Pre-Decimal (1952-1971)".
