This marble is another serious slice of art glass marble history, made clear back in 1989, before anybody even knew what art glass marbles were! What's astounding, though, is that even back then, during the nascent period of Mark's career, you could already see the signs in this marble that he was going to go on to become one of the world's greatest marble artists ever. The filigrana canes are already lined up and constructed almost perfectly, and Mark has gone on to take this filigrana marble style to levels of perfection that make your mind just freeze in wonder. This is your chance to own one of the early marbles which sent Mark down this beloved path. It is signed 'Matthews 1989'.
