Printed postcard of the Fosse no. 1 pit-head complex at Bully-Grenay in the Pas-de-Calais coalfield of northern France. The image shows the massive brick engine house and winding gear building in close view, with a tall chimney stack rising behind; large industrial boilers or steam drums are visible at ground level to the right, and a group of children stands in the rough grass of the foreground, providing a human scale against the imposing industrial structures.
