That's nice, where's that from?
It's from this http://www.amazon.co.uk/House-Horror-Complete-Creation-Collection/dp/1840680571The same place I got the two Hammer posters from. My edition has a different cover though.
I believe this was drawn by Roger Dean of numerous prog record covers fame - I'm pretty sure that it was in his (first) career retrospective
Interesting that he bothered to put a vest on the girl.
