Harley Quinn #6

Harley Quinn takes center stage in her red-and-black harlequin costume, playfully brandishing what appears to be a cork-stoppered vial while the looming green silhouette of the Riddler hovers behind her, surrounded by question marks and riddles scrawled across the background. Terry Dodson and Rachel Dodson's cover perfectly captures Harley's mischievous confidence as she squares off — at least thematically — against Gotham's prince of puzzles. With Karl Kesel at the helm for "Who Wants to Rob a Millionaire?", this 2001 issue promises a delightful collision of chaos and cleverness.
