Continuity mistake: During the election meeting held at the saloon, there's a large sign that reads "Capitol City Here We Come" on the wall by the stairs. We see this sign in numerous shots. When Valance enters the saloon there's still a sign on that wall by the stairs, but now the painted handwriting on this sign is different. Moreover, the original sign that had been by the stairs is now up on the side wall of the saloon, where Valance and his thugs stand; note the handwriting. (01:09:20 - 01:13:45)
