PM37 150th anniversary of the Football Association: Football Heroes
9 May 2013
Retail booklet containing 6 stamps, 4 x 1st class red definitives and 1st class stamps showing George Best and Booby Moore.
We have found some booklets with short phosphor bands - and quite variable.
1. Slightly short on definitives, much shorter on both footballers.
2. Slightly short on definitives, short on Booby Moore, but 100% on George Best.
This is an interesting situation: normally a short phosphor variety occurs when there is misregistration of the ink cylinders and the phosphor is set lower than the others. That would result in all stamps having short bands. But type 2 shows that the phosphor 'squares' on the special stamps were not set at the same height, resulting in normal phosphor on the George Best stamp and short phosphor on the Bobby Moore.
