Original copy of Ted Fujita's color map of the 1974 superoutbreak tornadoes (signed by Dr. Greg Forbes)

Scarce copy of the Final Edition map "Superoutbreak Tornadoes of April 3-4, 1974", a 17x22" color poster published by tornado expert Ted Fujita of the University of Chicago in April 1975, showing the tracks of the 148 tornadoes in the April 3-4, 1974 Superoutbreak, a table of the tornado information, and small graphics of the outbreak statistics. Slightly faded from age in the margins. Greg Forbes was part of Fujita's damage survey team and has signed the poster near where he is named on it.
