YOU said Buster couldn't possibly be funnier than in "Seven Chances" and "The Navigator." It couldn't happen. Well, it HAS happened. Never has he packed more laughs and excitement to the second than in his greatest film, "Go West." WITH BROWN EYES, THE FIRST COW EVER TO BE STARRED IN THE FILMS. (Print Ad- Cashmere Valley Record, ((Cashmere, Wash.)) 31 December 1925)
