I've often gazed at the Ivon Hitchens mural which adorns the now grandly-named Kennedy Hall in C (can't find the sharp symbol on this keyboard) House and speculated on how to extricate it without the building falling down. Not that this wouldn't be a Very Good Thing as long as the insurance was up to date, but the "work of art" wouldn't be worth much if the chunks of plaster got smashed. Particularly amusing would be the point where someone realised that couldn't get it through the door . . .
