You will recall earlier pictures of the new 1st class double-head 'flame-orange' stamp: the later image of the full sheet being quite different in shade to the publicity photos of the single stamp.
Well we don't have the single stamps yet but we do have the miniature sheet. As you can see from this scan of the actual sheet, the colour is very similar to that of the 'whole sheet' image shown above, and totally different to the publicity image and the Stamp Cards (see below).
The publicity image for the Machin pane is probably closest to the actual thing, with the background printed silver on white. The perforations are as usual, with two holes beloe the elliptical hole. As predicted these new self-adhesive stamps have security features (uninterrupted cuts of type I as on sheet stamps), security code MPIL (for prestige book) at top right, and MA10 (for 2010) to the left of the forehead.
The Seahorse PSB pane is printed silver on cream, not silver on white, and the loose ones we have been supplied with barely include the whole diadem, whereas in the book the full pane includes the whole of the left frame of the original stamp design. The stamps are well produced, but.....
Plans, intentions, publicity, marketing and reality.
Mock-ups are just that - we shouldn't put too much reliance on them actually showing how the stamps/panes will turn out in reality. To be fair, Royal Mail always say that they are working images - in the 6-12 months before they are actually issued - but is it too much to hope that the images and descriptions in their own Philatelic Bulletins might be accurate as soon as the stamps have been approved and printed?
The stamp cards for the 6 May stamps show the 1st class stamp in the colour we thought it should have been in - and possibly the colour that Royal Mail intended. Sadly the actual stamps are rather insipid compared with these:
