This week, during a period of strikes in the UK, we have banners and placards on the Post. As nurses here have never before gone on strike, there is no stock of protest materials. So we see hand-made, home-made signs created with whatever are to hand. Pictured are nurses outside Kings College Hospital, London, earlier this month, publicising their message by means of scale, typeface, and brilliant colours (and perhaps a reference to Manchester United?)
