Just bought a package of quite cheap records and found a signed Dire Straits Making Movies cover amongst the lot.
There are even two photos of John Illsey, the bass player, included - but there is also a scribble next to his signature.
Any chance this could be real ? Thanks for the input !
Addition: I received an offer for a signed Brothers in Arms CD booklet. I can only recognize a forgery - comparing to the Illsey signature. But maybe I am wrong ?
