The Joker’s plot to turn Gotham into a hell of technology-inspired madness continues full steam, and with Batman out of the picture, it seems Robin’s nothing more than a minor nuisance for the madman.
In order for Robin to convince Gotham and Joker are still around, he places a hologram of Batman. While Joker sabotages a telephone company he learns that Robin is displaying these holograms, and that Robin is alone in Gotham.
Note: This issue features three variant covers that came with holographic cards, painted by Jim Aparo, Tom Mandrake, and Chris Sprouse (with Dick Giordano inking), respectively. A fourth "newsstand" edition was done by Kevin Maguire, which did not feature the card.
