Aha! You guessed wrong!
This is a favour for the aforementioned ageing Navigator who wants to aquire said artwork, get it signed by half a dozen ex-Staish's and auction it for H4H. He was directed to me as a good starting point, but I have no knowledge of this print, hence the post.
As far as I know, 'There is no appetite' for any artwork commemorating Lyneham closure - we are going to spend all spare cash on beer & fighting.
