This is an antique or vintage embossed metal instructional plaque, originally mounted to the side of a soda-acid chemical fire extinguisher. The plaque is constructed from a copper-alloy metal, likely brass or copper, and is formed into a classic shield shape featuring a patriotic motif. The upper section displays the embossed letters U.S. at the center, flanked by star clusters at the top and corners. The central portion of the shield contains the instructional text FOR FIRE TURN BOTTOM END UP in high-relief lettering. The lower section is decorated with seven vertical stripes, completing the stars and stripes design. These plaques were standard on early 20th-century fire extinguishers that utilized a chemical reaction triggered by inverting the canister. No maker's mark or manufacturer name is present on the plaque. Dimensions: Approximately 5 to 6 inches in height.
