The original of this, as with many of the pencil-type drawings you often see, are/were done by a chap in Northern Ireland.
He's "done" quite a lot of this type of picture for many artistes.
Let me have a look around. I think I might be able to find his name. I actually think an ex-girlfriend bought me a print of one of this chap's FM etchings.
Leave it with me...
