Cambridge Posters - NOT amateur radio

All around the city you can see posters. These were in Bene't St. The yellow one is advertising my wife's concert on April 7th. In the background is Old School Lane, the site of the original Cavendish Laboratories, where many a Nobel Prize was won. The world famous Kings College Chapel is about 300m away.
