This flask was most likely made by Emil J. Larson of Vineland NJ in the 1930's. Larson worked as a blower for Dorflinger Glass before losing his job. He later joined three other men and made glass for Durand in 1924. Larson was the gaffer in this shop. After Durand closed in 1931 Larson did some blowing for Wheaton. By the mid-30's he was blowing his own glass in a one pot shop in Vineland. Larson did many reproductions of Stiegel glass and this flask appears to be one of those.
