Coincidentally (if it's any help) I was browsing through one of the bookstalls at the PFA Rally at Kemble a couple of weeks ago and came across a softbacked book about the history of Tangmere. It includes a photo of the print, albeit in black and white.
Can't remember the title; just "Tangmere" I think. Looked like it might be one in a series of airfield histories. If you can find the book there may be a reference for the photo that might throw some light on subject
