This vintage mackinaw coat was made by Sheuerman Bros of Des Moines, Iowa. It is double breasted, with broad lapels, patch pockets and a buttoned belt. The coat is gray with a subtle overcheck. As is typical of mackinaw coats of this era, it is unlined. The construction appears that there was a vent that has been closed, possibly the coat was shortened. The label is typically 1920s, with a black background and yellow lettering. Sheuerman’s slogan was “from sheep to shape”.
