Chris has sent this picture of the collectors set of Robins from Trafalgar Square.
If you zoom in, you can see that the grey printing ROYAL MAIL in the background shows MA12 just above the 'g' of the weight. So when this is repeated next year, it will be interesting to see which offices didn't use all their 2012 allocation! Post Office will undoubtedly say that it is for stock control but sceptics (and cynics) will say that it is so that the collector will buy them again next year.
Two more pictures, from Richard:
