Hi elizad27,
I recall seeing a print in a pub in Driffield, East Yorkshire. It depicts a Hurricane (I think) or maybe a Spitfire, seen through the broken glass window of a WW2 RAF Control Tower. The area of the picture where the glass is broken reveals a 1940 image, as if seen 'live' at that time: the area where the glass is intact shows the interior of the Control Tower 'live' at the time of painting the picture, maybe 30 years after the war ended. ..
IF YOU WOULD CARE TO SELL IT TO ME, I WOULD BE VERY INTERESTED, but I have no idea of its value. What number (of how many) is the print?
Rgds.
