Vaquero is a Wild West style font.
It is characteristic of a lot of western era signage, with super-narrow characters and unusual decorative spurs and serifs. There are some similarities in Vaquero to some of our other western fonts. It sort of ties together the historic tradition of western era type and the more fanciful tradition of romantic type derived from the era of the wild west. It has the width, height and general letter shapes of Academy, but the decorative elements are similar to more fanciful fonts like Riudoso.
The result is very evocative of the old west.
