|Chess board signed by Bobby Fischer and Boris Spassky.|
In the days before professional chess players used databases and powerful chess engines to prepare for their opponents, top-quality chess literature represented cutting-edge 'technology.' Prior to his titanic World Championship with Boris Spassky, Bobby Fischer carried around a copy of Weltgeschichte des Schachs - 27 - Spassky so he could study the games of his opponent in great detail. The book did not feature any annotations but Fischer's own handwritten notes can be seen on the pages.
