Vintage farm and agriculture signs run the gamut from brand advertising to cattle and tractor crossing warnings and no trespassing signs. Some staples for collectors include signs advertising feed, milkers, waterers, and fertilizers; ads for dairy, fruit, and vegetable growers, cattle ranchers, Farm Bureau or Cooperative Member signs, and even hand-made or painted signs advertising a specific farm or ranch business.

Some notable brands include John Deere (but beware of reproductions), International Harvester, DeLaval Cream Separators, McCormick, and Farmall.
