A couple look at children’s apparel in the illuminated shop window of the clothing store Bahlmann & Co. on the Nieuwendijk in Amsterdam. The little dresses are neatly arranged by colour, creating diagonal strokes of red, light blue and white. Nocturnally lit shop windows, made possible by the introduction of electric light, were new at the end of the 19th century. This made the city safer as well as livelier at night.
