Andy, I have been dreaming of finding a Michael Harris crizzle stone for some time (since I read Mark Hill's book), I heard of a find (must have been yours) at an auction via the grapevine and felt as much hope as jealousy. This stone does not have the size of those I have seen photographed and I have not seen one in the 'flesh' to compare Father's and son's but they all look more than fantastic to me.
I must also confess to some more outrageous good fortune, about two years ago I bought a fish vase (faceted) signed by Michael Harris for a song at a local car boot sale. At the time my interest in glass was mostly Scandinavian and I did not know what I had bought (I knew it was nice) until I got home and did a little research, I was speechless (well nearly). The colours of the fish vase are purples, blues, greens and amber, I was converted.
Fantastic finds are still out there but if everyone else can just form an orderly queue.....
Some photos of the fish vase follow, the colours are more vibrant to the eye than they appear in these snaps.
