This vintage mackinaw coat was made in the early 1950s for Montgomery Ward and was sold under their Windward Outdoor Clothing label. It is made of red, black and gray plaid mackinaw cloth, with a half-belt back and button on front belt. It bears a 1949 Amalgamated Clothing Workers of America union label, and a Windward label before the inclusion of the (R) symbol, which, combined with the quilted lining and subtle details, put the dating solidly in the early 1950s. The overall style of the coat from the outside is nearly unchanged from its first wave of popularity around 1935.
