Beginning in the 1750s, some American insurance companies issued metal fire marks to policyholders to signify that their property was insured against fire damage. The fire marks bore the name and/or symbol of the insurer, and some included the customer’s policy number. The company or agent would then affix the mark to the policyholder’s home or business. For owners the mark served as proof of insurance and a deterrent against arson. For insurance companies the mark served as a form of advertising, and alerted volunteer firefighters that the property was insured.
The Firemen’s Insurance Company of New Orleans, Louisiana issued this fire mark around 1875. The Firemen’s Insurance fire mark consisted of a raised image of an early fire hydrant with hose attached, surrounded by the letters F.I. Co. in the center of a cast iron oval. This fire mark’s symbol is taken from the imagery associated with the Fire Association of Philadelphia. The Firemen’s Insurance Company of New Orleans operated from 1875 until 1898.
