One of the all-time great Italian Western trailers, for one of the all-time great Italian Westerns: 1970's ¡VAMOS A MATAR, COMPAÑEROS! (aka COMPAÑEROS), directed by Sergio Corbucci and starring Tomas Milian, Franco Nero and Jack Palance. Music by the always incredible Ennio Morricone, naturally.
Somehow this trailer didn't make it to the otherwise excellent US DVD release (initially from Anchor Bay, now available from Blue Underground), though if memory serves it was included on the (once much sought after) DJANGO, KILL! Japanese laserdisc.
