I believe Archimedes to be correct - although I first saw (and copied and kept) it on the wall of one of the old Sqn buildings on a disused airfield in Lincolnshire in the days when kids could play in and around many of them. I'm not 100% sure but it was either Kirmington (long before it became Humberside Airport) or North Killingholme. It certainly wasn't Goxhill, 'cos that still had a load of abandoned hulks of US aircraft on it.
Again I haven't seen an original in print, but I have seen reference to it in connection with Noel Coward.
