Marwen Films

(1983)
Logo: On a black background, after a few seconds, we fade onto a dark yellow background, containing a very thin ring with the letters "MW". Next to it are the words "  M   AR   W   EN Films " above and "Presenta" under. It all fades out.

Technique: Just the fading.

Music/Sounds: A triumphant fanfare which sounds likely similar to the Columbia Pictures logo.

Availability: Ultra rare. Only known to be seen on Alguien mató su inocencia.
