This is Bob Marx"s most significant book concerning the shipwrecks of the world and is literally a culmination of more than 50 years of experience and research. He covers all known shipwrecks of both the Old World and New World whose cargoes contained at least $10 million worth of treasures. The World"s Richest Wrecks contained many maps collected by Marx and more than 100 photos of shipwrecks treasures and diving salvage operations, many in full color!
