From Master Marble Maker Dave McCullough, producing marbles at JABO Inc on June 4th 2009 with the Joker Team. The Ultra Run was one of the early successful crystal based runs with many of the marbles exhibiting a good UV reaction. Among the most sought after from this run are the heave "Oxblood and Blue" Radioactive Spider-mans, also the heavy and or busy "Blood Vipers Nests" and many other combinations which enhance any collection.
