Although both pins are EDF0012, the original (top) pin has the wording 'sustainability partner' whilst the subsequent print uses the wording 'official partner'. Notice too, that on the original pin, the logo has a silver border, whereas on the later pin it does not. The backs of the pins are identical other than the original pin seems to have a more defined texture.
Looking back at information from EDF, I noticed that between December 2011 and May 2012, some of the issue sizes increased - this pin being one of them. Originally the issue size was 1,500 but this was increased to 20,500 nearer the Games. Presumably EDF decided to use this for promotional purposes during the Games and had more produced, but with the new wording.
This is not the only pin in their range that changed the wording and increased in number...
EDF0008 | Olympic 1 YTG | 1,000 > 1,500 |
EDF0012 | Olympic Union Flag | 1,500 > 20,500 |
EDF0013 | Olympic 300 DTG | 500 > 1,000 |
EDF0014 | Paralympic 300DTG | 1,000 > 1,700 |
EDF0017 | Paralympic 200DTG | 600 > 1,300 |
EDF0018 | Paralympic 100 DTG | 600 > 1,000 |
EDF0019 | Olympic 200DTG | 500 > 1,000 |
EDF0020 | Olympic 100DTG | 600 > 1,100 |
EDF0021 | Olympic Games Time | 600 > 1,100 |
I am assuming that all the smaller sizes were produced as 'sustainability partner pins' and all the increases were produced as 'official partner' pins. I also assume that the 'reprints' were to provide enough sock to issue the countdown boxed sets seen during the Olympic and Paralympic Games. I will update the catalogue to reflect the two varieties of each pin and the different issue sizes.
Not only have we seen variations in wording and issue sizes with he EDF countdown pins, but also in the small TM or (R) markings that appear alongside the logo on the pin. To date we have seen variations in pins EDF0014 and EDF0028 where they may use either the TM - Trademark symbol, the (R) - Registered design symbol or no symbol at all.
Thanks to Angela for pointing out the difference which prompted me to investigate further.
