I went to see the Museum of 51 exhibition at the Royal Festival Hall a while back, which is about the Festival of Britain. Basically it was a festival in 1951 to celebrate 100 years since the Great Exhibition and cheer people up in grey, rationed post-war London. As well as films, shows, fairs and so on, there were shows of housing and interiors, to show people what they could look forward to after rebuilding and the end of rationing (everything available for sale in WWII was simple and utilitarian and rationed). My dad went to pretty much all the events, seeing as they were mostly around the corner from him in Battersea.
