This is an extremely rare marble from the husband/wife glass team of Mary Mullaney and Ralph Mossman. They have been blowing glass since clear back in 1985, and have made VERY few marbles/spheres over the years, and typically make paperweights and other objects with their milli. They also make other amazing glass objects such as vases, stemware, perfume bottles and other sculpture. The milli is just absolutely PACKED into their marbles, and the result is an amazingly colorful and beautiful spherical tribute to a milli style we all love so much. This is the only one I've ever sold in this size with these particular milli, so this is a rare opportunity to own an amazing gem from this very accomplished glass couple!! Signed 'Heron 99'.
