1920’s/30’s Hercules Black wool sweater vest

1920’s/30’s “The Hercules Coat” black wool knit sweater vest. Another great almost 100 year old sweater this time by Hercules. A thinner black knit with some nice inlayed checkered details and white trim accents. Some nicks and well done hidden repairs but overall great condition for the age.
