DETECTIVE COMICS #475 FACSIMILE EDITION

ENTER THE JOKER FISH! Holy mackerel! The Joker has surfaced again in Gotham City, enacting his most insane plan yet: a chemical concoction that fixes fish up and down the coast with the Joker’s own ghastly grimace! Now, the Clown Prince of Cod wants to cash in on the copyright--and will gleefully eliminate bureaucrat after bureaucrat until he gets what he’s after!
