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.
