I'd love to have it as a print but you know what I'd *really* like to have...? A figurine. No idea how you'd do it, given the thin lines, but I might ask an artist friend if she knows an out-of-work sculptor who'd have a crack....
Brian-DC - I reckon I'll have a go at scanning in to photoshop, bleach out the colours, erase for a while and hopefully end up with something that matches the white of my walls as background with just a suggestion of the cave art coming off the paper. Blown up a bit that'd look pretty good, I think....
And thanks for the images, Rasi - now my desktop wallpaper...
