This vintage coat was made by Albert Richard in Milwaukee, Wisconsin in 1946. It is interlined with “Spun Sun” fiberglass insulation, pioneered by Albert Richard immediately after WWII. This model can be seen in the advertisement below. This is the early style “Spun Sun” fabric, before the introduction of the (R) symbol in 1947. Albert Richard was sold and relocated in 1952, closing shortly thereafter. This coat has a three button front, a broad collar and two flapped hip pockets.
