This is one of my old Hellraiser folio designs. They were a collection of parchment sheets featuring conjectural drawings from the hand of Philip LeMarchand. This was back before the sheer inanity of the Hellraiser mythos became too much to bear. You should be able to right click and open the image in another tab to nick the full resolution version. If not, I've posted the high rez image to Google Docs. This was originally sized to print out at roughly 10" by 10", but you could push it a bit further without too much trouble.
If you're willing to put in a little effort this could make a very nice framed display piece. Just print it out on some aged paper and then hand tint the design elements as you see fit. I was able to get some really nice results using colored pencils, particularly with the degree markings. If you lightly fill in each block with red or brown and then edge shade it you get a very cool looking effect. I'd love to see what you come up with.
If you like this sort of thing I have dozens of other designs I can post. All I ask is that you provide credit and don't sell anything incorporating it, in line with the Creative Commons license for everything here on Propnomicon.
