This ticket and that for The Olympic Youth Camp (below) appear to be a lot rarer than I had originally understood.
Of the 5,003,204 tickets printed for the 355 sessions of events at the Games, this complimentary ticket is 1 of only 27,970 produced (0.5%). These were provided to private renters in the city in recompense for their participation a 'Bed-Finding Campaign' to provide accommodation to spectators.
