World's Finest #245

Dinah Lance (aka, our favorite heroine Black Canary) goes undercover at a hospital in order to find out more about "The Man Bear". She undresses from her Black Canary costume, and gets some information from a nurse at a desk.

She then walks into an empty area of the hospital, only to get chloroformed by one of the crooks.

This is one of Black Canary's classic scenes!
