| Notes: | This booklet (RB5) was released very late in the year with Special Backing paper added AND the stamps have DULL phosphor so is quite difficult to find as it had a short shelf life.
The previous booklet, the original RB4c booklet, has the blank paper backing (BPB) and is listed elsewhere on the site if stocks are still available. |
