"Collect all 14 super transfers to complete your calendar", says the envelope (not shown, but green — apparently).
We missed the auction for the above four sheets, but Bevy1703 kindly gave us permission to use the photos.
This series does beg some interesting questions: the events depicted seem very British (Fireworks in November & a beach scene in August, for example), yet the text on the sheets is very awkward for ordinary English.

And why the serial numbers SP-1 to SP-14? Letraset used "SP" for Special Sheets, but these are probably not Specials — & the numbers would be very much higher. It's unusual not to use "L", "PR" or "LP" at this date…
