This might be one of the places to put this question. and we'd be grateful for any help. The question is, would a print purportedly signed by Johnnie Johnson (the highest scoring Western Allied pilot against Luftwaffe aircraft, thus becoming the British, and Western Allied flying ace, with the greatest number of victories in the European Theatre of World War II) be really worth Â£50.00 and how would we know it's genuine? In a local antiques emporium, there's print titled "RAF Sealand" and showing what it says is a Spitfire LF.16E TF-248 "DW-A" 610 (County of Chester Squadron) Royal Auxiliary Air Force. The Print has at the bottom of it: (C) Dugald Cameron 1987 No.248 Also on the print are the words "June 1956 Squadron prints Ltd. Glasgow." The emporium is selling the print as "Spitfire Print, signed by four pilots, including Johnnie Johnson, and there are four signatures including what appears to be Johnson's signature. The Print "is a bargain" they say, at Â£50.00. If this is a genuine piece and the signtures are genuine, our little group would buy it and donate it to a charity yet to be decided.
