Following on from the Walsall-printed 2nd class Business Sheet (reported here) we can now show the first booklet reported on security backing paper (also printed by Walsall).
GW has sent this image of the Long To Reign 6x 1st booklet, with O15R year code. These ought to be fairly widespread but without knowing the size of the printing, it is impossible to know whether it will be plentiful.
Further printing with O16R year code will surely appear later this year and those will also have the printing on the backing paper, but it may be that the O15R supplies will not be common.
UPDATE 7 February 2016
2nd class booklets of 12 and 1s Large booklets of 4 have now been found with the new backing. Details are:
6x1st purple - packing date 06/01/16 and 12/01/16
12x2nd - packing date 23/11/15
4x1st - packing date 21/12/15
All have 2015 year code, and have the more recent duller phosphor.
Interesting to note that the Penny Red booklet sold on 18 February has no security printing on the backing cover.
