Thermometer

One small thermometer advertising "The F.D. Stella Products Co." The thermometer consists of a glass tube of mercury with Fahrenheit and Celsius scales that is held inside a vertical, oval-shaped clear plastic tube with white plastic end caps. An aluminum hook is attached to the upper end cap to allow the thermometer to be hung from a metal grate shelf in a refrigerator or freezer. A narrow white paper card on the back side of the thermometer has blue printed text that reads "The F.D. Stella Products Co., Food Service Equipment, 7000 Fenkell Ave., Detroit, MI 48238," and "(313) 341-6400." A blue image of the head of a Viking man is printed on the left side of the text and the circular "NSF [National Sanitation Foundation]" logo is printed at the right.
