In my "local" there's a blown up photo of the outside of the pub from what appears to be pre-war times. Nothing remarkable about that except there's a large number of people, cars, bikes and sidecars around and a large banner proclaiming "FINISH".
Looking more closely at the banner there's a logo that looks to have the words "Motor Cycling" on it. I thought it might be the MCC but hunting around the net, the closest thing I can find to the script / font used on the banner looks to be from Motor Cycling magazine - see http://www.dropbears.com/c/classicmemories/gallery/motorcycling_1900-1949/index.htm
Anyone any ideas of the event? The pub is The George in the Tree and the town is Balsall Common.
Next time I'm passing with a camera I'll get a photo.
