"Mascara Negra" is Spanish for "Black Mask."
I have forgotten every bit of Spanish I learned in school, so I am going to be of no help to you with this one.
She is a masked mystery crimefighter, appearing in the Spanish pulp El Encapuchado and in a weekly comic strip in Coyote. She appears in a tight-fitting (Is there any other kind in Comicbookland?) with white gloves and a long flowing cape. And there is a reporter named Bob.
That's about all can tell you except there are guns and cars and derring-do.
This is a compilation from the first several issues of Coyote that Mascara Negra appeared in. The artwork -- which ismpretty neat -- is evidently by Adriano Blasco.
This Mascara Negra should not be confused with the title character in a 1982 Spanish television show, Mascara Negro: that "Black Mask" is Don Carlos, a Spanish Zorro. Nor should it be confused with Mascara Negro, a short gay porn film from Brazil, circa 2010,
