17 February 2016 - Royal Mail 500
18 February 2016 - 175th Anniversary of the Penny Red
The Royal Mail 500 miniature sheet was issued on 17 February.
The following day the same stamps were issued in a different format in the 1d Red Anniversary prestige stamp book. It is likely, following precedent, that the stamps will be assigned individual catalogue numbers, with spaces in preprinted albums.
These stamps are from the PSB (SG DY16) numbered SG 3802-5.
