Nothing distinguished what trendy young people in my day called a “den” so much as precise, geometrical framed prints. For me it was sometimes a tramcar, an aeroplane but most usually a car. All they needed was a modest caption with title, date and maybe a few technical facts. Prints like that made a statement. Maybe they are now passé but I still treasure some; Glasgow tramcars recall my youth, aircraft like a BEA Pionair (a Dakota really) in which I made landmark flights to London. I have one of a 602 (City of Glasgow) Squadron Spitfire that flew from RAF Westhampnett, the Goodwood circuit where I covered races and drove many memorable laps.
