“Harley Quinn Day” @ Participating Comic Book Retailers
September 23, 2017
This year, Batman Day is getting a mirthful makeover and is being rechristened as “Harley Quinn Day”. Head to your participating comic book retailers to celebrate all things Harley Quinn and to snag some discounts and freebies that honor her on her 25th Anniversary.
