The primary vehicle of a cowboy is a horse. John Steinbeck wrote: “A man on a horse is spiritually, as well as physically, bigger than a man on foot.”

 As soon as he arrives in Redskincity, Tintin starts looking for a horse.

 The obsession with movement:

 Tintin in America is one of the adventures which refers most to the fast-paced films of the time.

 Hergé is concerned with the effectiveness of the cutting and framing, entirely dedicated to moving images. This figurine from Tintin in America (coloured version), page 32, vignette C2, shows Tintin's first gallop. The way that the horse is designed makes us think of a typical animal cartoon!
