Mark control board of the Carl Funke colliery

The control marker board of the former Carl Funke colliery in Essen clearly shows the structure of mining in the period of high industrialisation around 1900. The workforces of the collieries comprise thousands, whose underground production was not based on machines but on manual labour, so that miners were not listed with their names at the beginning and the end of their shifts but were only perceived as anonymous numbers.
