Aerbabe - you took the words out of my mouth (or at least off my keyboard)...
My old 1/4mil and London Heliroutes chart have just gone to my mate's Army Cadet Unit - they are affiliated to the Army Air Corps so it's something for the kids to adorn the walls of their unit with. They seem to like it.
Worth trying to find a local ATC Squadron who are bound to snap them up.
