This is a Lacoste Izod cardigan in a university blue color. Lacoste is a french company founded in 1933 by Ren? Lacoste, best known for their tennis shirts featuring a crocodile logo. In 1952 Lacoste was brought to the U.S. when U.S. brand Izod bought 50% of the rights to market Lacoste in the U.S. The brand was marketed as the "the status symbol of the competent sportsman," and became the prominent brand for high class "preppy" Americans. This partnership lasted until 1993 but this cardigan is from the 1970's/80's when the two brands were interchangeable in the U.S. This cardigan is a piece of fashion history and a great vintage item.
