Miller Brewing Company introduced Magnum Malt Liquor in the 1980s, aiming to capture a segment of the market with a higher alcohol content beverage. Promotional mirrors like this one were a popular form of advertising, offering a functional and decorative item for bars and retailers.
The guy who sold me the mirror won it in the late '80s playing darts while drinking at a stranger's house he met at the bar earlier in the night.
