5/10: McDonald's Pins

Over the weekend a few sellers on eBay have been advertising McDonald's London 2012 pins. There are 4 designs featuring the London 2012 logo with the McD Arches. 3 of the pins also feature London icons
of a Guard, Big Ben and a bus. They appear to be printed rather than enamel and no word on manufacturer.

I've heard conflicting information that these may be retail pins or staff only pins. If anyone has any further facts on these pins, feel free to add a comment.
