Err, just to go off topic for mo, if you'll pardon me, since GW I has been mentioned.
I have one of Rondot's GW I Jag prints, wot I won as the second or third prizes in the Xmas Draw in the Colt Mess that year. It's signed by all the pilots wot took part.
Any one know if that was a one off for the draw or, if not, many signed copies were made?
Ta, sorry to interrupt.....
