February 13 - Last week, the Olympic volunteer programmer held it's first induction briefing for the first 10,000 Gamesmakers. The training of the volunteers is being carried out in part by McDonald's and there were reports of some McDonald's representatives wearing a silver pin.
We believe this is the pin in question and combines a silver London 2012 logo including coloured Olympic rings with the McDonald's name (but not the logo).
We have been told that the issue size for this pin is 200 pieces. If true, that would make this an internal only pin.
