Batman Day Event Planned for Sydney Opera House on September 19th

DC and HBO Max are organizing a major Batman Day event at the Sydney Opera House this Saturday, September 19th, to mark 87 years since the character's debut in Detective Comics. The celebration includes free giveaways, signings, cosplay opportunities, charity drives, and new hardcover releases such as "Batman of Two Worlds" by Matt Fraction and Javi Fernández. A viral stunt recently showed Batman on top of the Opera House to tease the upcoming gathering at 6 pm.
