A black and white cowboy logo typically features a simplified and stylized image of a cowboy or western-themed iconography. The logo may be primarily black with white accents, or vice versa. Black and white cowboy logos aim to capture the rugged, independent spirit of the American West and evoke a sense of nostalgia and tradition. The use of black and white can also lend a timeless and classic quality to the logo design.
Additionally, there are some brand designers who are interested in designing logos to specifically sell them in logo design marketplaces like here.
If you want to purchase a logo from a designer and don't want it to be present even on inspirational design sites after purchase, make sure to request this from them once you've purchased it.
