These utility coveralls are a former employee uniform from Shell Gas and Oil in brown cotton, featuring a zipper closure down the front of the torso, long sleeves, pockets and the company's signature logo on the left shoulder.

The size corresponds to a modern medium, although this is suitable for multiple sizes. Please see measurements for the right fit. 

This is in good condition overall, although please note that this is a vintage item and presents with signs of wear consistent with age and use.
