Worker Caps -
Almost every commercial firm at one time or another has had a patch made for their workers. Farmers, auto dealers, railroads, filling stations, groceries and fire departments sewed patches first on their uniforms and later on caps. Originally patches were felt, but later the merrow overlock method put stitching on a canvas base. Each Industry Patch cap is a One of A Kind and has an original and vintage patch usually, but not always, from the 1940's and 1950's.
As the caps below are from different eras, the construction varies slightly. Generally, they are round, soft-crowns, 12 oz. wool flannel, with a hair canvas backing and leather sweat band. Visors have a dark green under-visor. Particulars are in the product description.
