Pre-state issues should exist for all counties, but not all are accounted for. Most counties would issue vehicle owners a number, and it would be up to the owner to display it on the vehicle. Examples include numbers painted on bumpers; house numbers attached to a leather strip; numbers engraved in a block of wood. Most were porcelain, though, and contracted to Ingram-Richardson Mfg. Co. in Beaver Falls, Pennsylvania or Baltimore Enamel and Novelty Co. in Maryland. To cover the cost of making porcelains, many examples feature advertising, almost always by the dealer that sold the car.
