Update 2 on Pictorial Faststamps - (see initial report here)
Royal Mail have confirmed that the set of 6 1st class Bird Faststamps supplied to Bureau customers will be a 'sheetlet', ie they will be on one undivided sheet of backing paper (see above) in two rows of three stamps, the same format as the official first day cover.
Originally Royal Mail had said that the Faststamp* was a Post Office product and not a philatelic product, so would not be issued from the Bureau. When it was pointed out to them that the original Frama labels issued in 1984 (right) were the subject of special distribution from the Bureau, with a specially designed FDC and FD postmarks at each of the trial sites, Royal Mail had a rethink, hence the appearance of the Machin Faststamps pack.
(* Incidentally, Royal Mail and Post Office Ltd use the term Post & Go Stamp, although 'Faststamp' had been adopted by collectors and dealers long before, and that name is used in Stanley Gibbons' catalogues.)
The arrangement of the stamps on the rolls in the Post & Go machines would produce this sort of arrangement on each vertical strip if the normal 5 different values was chosen. You will note that the vertical 'se-tenant' pairings are different to those on the sheetlet
