Detective Comics #432

In "The Great Rip-Off Mystery!", Batman dives into a baffling crime when a murdered courier is found with a briefcase full of torn currency halves, each piece a different denomination. Written by Frank Robbins and brought to life with sharp detail by artist Bob Brown and inker Murphy Anderson, the story unfolds with the kind of crisp, noir-tinged mystery that defined Batman in the early '70s. The cover, a striking double portrait by Dick Giordano, captures the tension of the case in bold, expressive lines.
