Batgirl Reveals her Secret!

From the early '70's: Batgirl decides to divulge her greatest secret to her motorcycle mechanic, who just had the snot beat beat out of him by some thugs who saw the Masked Maiden leave his shop. They were trying to force him to tell them who Batgirl really was, but he didn't have the answer. Now he knows. This doesn't seem like a good decision to me.
