There used to be a shop on Selsdon Road in South Croydon which did mail order aircraft slides and prints - think it might have been Brian Stainer? I never went there as I bought postcards as a lad (or raided airline offices) but wasn't much interested in other people's pics.
Edit: quick research suggests definitely not Brian Stainer, does anyone else recall it? Sure they used to advertise in Air Pictorial, etc...
