This pressbook for Fort Vengeance is more interesting than the movie. The campaign art promoted the "red savage" theme in the usual way (war paint, axe, feathers, and menacing face). Rita Moreno starred in a cardboard role and sold cardboard bread in a Hollywood Bread tie-in. Interesting to note that bread was a common tie-in (called tie-up here) with westerns, especially for television. The pressbook mentions "the movie was filmed in color to bring out the scenic splendor of the Canadian Northwest, but the movie was shot indoors and outdoors in California.
