It's a very, very scarce piece, made by Michael Harris, Greg.
It's utterly fabulous, one of my very best pieces - and it's really, really cuddly - you can hold it in your arms like a baby - but it's better behaved. :sun:
Ron Wheeler recently found and sold a signed one.
(he using an image of it as his collector's club membership card - see here:-http://www.artiusglass.co.uk/id32.html
Peter Elliot had one which he sold perhaps a couple of years ago - it was at the same Fair as Ron sold his first signed Crizzle Stone. Over the years I have been told of two others - one slightly smaller but signed, and there's mine. So only 5 are known. And two of those are hearsay!
It's from very early on at Mdina - it's in "plain" amethyst glass, with no silver salts included.
