This was my entry for the Legacies - A Batgirl fanzine, centered around Barbara Gordon, Cassandra Cain, Stephanie Brown and others.
For my piece I decided to re-imagine the classic 1966 Batman movie poster featuring Adam West & Burt Ward. I've always entertained the idea of Cass Cain being 'Batman' with Stephanie Brown as her 'Robin' (especially after reading about their team up in the early 2000s run of Batgirl).
