It looks like a quick Gary Moore to me, here's my two to compare to. The top of the 'G' looks good and the 'e' on Moore looks right with the little dot after it. I think it could be a very fast signing but good. Just my opinion though.
Yeah, and anothet thing I've just spotted; look at the 'From' on my 'After The War' - on the poster you have a 'From' that is rushed too, but notice that he does a capital F and R on both and they look identical to me,
