This is an underrated Silver Age DC GEM and one of the most important early Batgirl books outside of her first appearance.

Detective Comics #369 sits at the crossroads of Silver Age Batman evolution, Batgirl’s rise as a core DC character, and the transition toward more dynamic, modern storytelling.

Key significance:

• First Batgirl & Robin team-up
• Early showcase of Batgirl as an equal, not a sidekick
• Strong Neal Adams-era influence
• Catwoman cameo (last page)
• Recognized Batgirl key issue

This book helped cement Batgirl as a permanent pillar of the Batman universe.
