HUMOUR. An irreverent collection of eulogies, tributes and fond farewells to the many Christmas traditions and, well, other festive things that are threatened with extinction. From handwritten cards to coffee cremes, from Yule logs to thruppenny bits in Christmas puddings, from making paper chain decorations to carol singing, all of these and more are endangered, on the way out or on their last legs ... so what better time to celebrate them than Christmas itself.
