This recent auction sale is constructed of narrow loom denim of which the selvedge edge can be seen on the back side of both right and left side button & button hole plackets. The closely spaced white stitching with a large count per inch contrasts nicely with the dark indigo denim. Additional details including wreath & star donut type buttons, Cantripum script loomed neck label and United Garment Workers of America union label likely date this jacket to the 1930's. A similar jacket seen here was featured in the Vintage Clothing Auction of Rin Tanaka's 4th Annual Kulture Recycling Show, Inspiration in February 2012.
The Cantripum Brand Overalls Coats and Khaki Goods flange sign seen at the top of this post was pulled from the web some time ago and helped in identifying the script label of this jacket.
