Bagpuss, the Clangers and the Pogles – along with other fantastical creations by Oliver Postgate and Peter Firmin – are celebrated in a new book, The Art of Smallfilms (£25, Four Corner Books). Postgate’s son Daniel says: “I think what people like about their work is the integrity of the characters: you get the feeling that if the camera was off they would carry on with their lives.” The carefully hand-knitted puppets come from a time before computer graphics were the norm. Daniel, who is working on a new, CGI-free series of Clangers, says: “It was quite a unique way of making programmes – a homemade, make-and-do sort of way – and we’ll follow in that spirit.”
