Vintage 1950s French Railway Worker Jacket
Rare! 
Fashioned in duck canvas cotton.
These jackets were traditionally worn by French railway workers.
They feature large collar, button front and button cuffs. It also has its martingale strap to collar which was originally designed to tighten the garment for warmth and secure the collar against the wind. 
This jacket has a patch, fade, marks and signs of wear etc… which only adds to its vintage workwear charm and character.
Please see photos.
