Gifts from the Gods

Why?
a) left over at White City from the London 1908 Games
b) outside the BBC marking the London 1948 Games which were the first ever to be televised
c) whoo Jessica Ennis overshot by 11 miles
d) a Boris funded art initiative

Whatever the answer it was a quick last minute snap. I had a date with some dancing celebrities, but completely missed the boat :-(
