"The Great Criminal Geniuses" of Earth-2

The "definitive book on the subject" of the supervillains of Earth-2. This encyclopedic volume contains entries on the major villains of this alternate Earth (see Parallel-Worlds), including the Earth-2 versions of Lex Luthor, the Ultra-Humanite, Brain-Wave, and Professor Hugo Strange --with the glaring ommission of Colonel Future, the man "who caused Superman to disappear for a year" (SF No. 220, Jul 1982: "Where Off Earth Are You From?").
