Original Penguin (also known simply as Penguin) is an American clothing line. With roots in the 1950s and ‘60s, the brand specializes in clothing, footwear, and eyewear. The brand was introduced in 1955 by Munsingwear, a Minneapolis-based underwear and military garment manufacturer, when it launched the Original Penguin golf shirt in the United States. It was worn by Bob Hope and Bing Crosby for publicity, but the real advertising featured golfers Arnold Palmer, Dow Finsterwald and Jack Burke, Jr.
