Showcase '94 (1993-1994) #3

Two-Face, the Scarecrow, the Riddler, Mad Hatter and Poison Ivy are among the newcomers to enter Blackgate—and the prison's permanent residents aren't happy to have visitors! Then, Razorsharp and the Psyba-Rats star in a two-part adventure, and a framed Blue Beetle must make a seemingly impossible escape from a fortress prison.
