Square black-and-white image of a staircase leading into the hall of Frankfurt Central Station. The view goes up the staircase to the roof with its many skylights. The double metal railings on each side of the staircase have a bend at one landing. At the top centre of the image is a triangular warning sign with a train symbol. The sun shines from the right and illuminates the upper left staircase. Details of the roof are reflected in the clad walls of the staircase.
