IWC used a series of 100x35cm photos the Junkers Ju 52 and Spitfire to advertise their watches... I was lucky enough to get the series and three of them hung on my office wall for many years... now at home... The Junkers is certainly a classic and what a treat to ride in one... and over the Swiss mountains... Beautiful...
Good luck with the M9, hope it gets back to your hand quickly and in good condition...
