29 September 2008 - Regional Definitives 50th Anniversary
The first regional definitives were issued in 1959. Royal Mail marked this anniversary by the issue of a miniature sheet of 9 stamps utilising the designs for the 3d, 6d & 1s3d stamps of Scotland, Wales and Northern Ireland, all converted to 1st class values, and a prestige stamp book.
In the PSB some of the stamps on the individual country panes show differences from those on the mixed country pane. All are on white paper whereas the miniature sheet has a printed cream background to mimic the originals.
