On my first day in a landscape architecture office the kind lady at the drawing board behind mine asked ‘What have you done before?’. I told her, modestly, ‘degrees in philosophy and landscape architecture’. ‘Ah’, she said, wisely and with a soft Scots accent,’an apprenticeship in the post office would more use – the main thing we do here is tree stamping’. So, in memory of that happy day, I give you a scan of a very high-class set of tree stamps, which belonged to my former colleague Michael Lancaster. A very good designer and draughtsman, I can’t think what he used them for. The largest stamps were unused until I had a go with them recently. Just think how much use they could be for retrospective planning in Chinese cities!
