Justice League of America v2 #15

I think it's safe to say, this art is by Ed Benes?
Amazing two page spread showing Black Canary, Wonder Woman and Vixen captured and bound to a fancy contraption.

A very busty Wonder Woman is unconscious, front and center! A metal clamp gags Black Canary, who is also unconscious.

Superman looks on in shock, as a defiant Lex Luthor gloats, on the bottom right.
