Wonder Woman in her Golden Age glory.
In this scene, Wonder Woman is doing some investigating. She finds a hidden door and goes through it. In the next panel, she is being chloroformed by some thug. In her thought bubble she thinks "Oohhh -- Chloroform ...", and then passes out. She is carried over the shoulder.

Wonder Woman falls through a trap door straight into a net. Before she can escape, a woman clamps a chloroform soaked cloth over Wonder Woman's face.
A classic scene, and Wonder Woman's first chloroforming in the comics. She would go on to be chloroformed in the 1976 TV Series.
