For each painting or photograph, background information can be accessed. Spread out through the museum are miniature models from which the 3d images were created. There are a total of 54 paintings and photographs on display from artists such as Rembrandt, Bierstadt, Monet. Included is also a special exhibition of photographs taken in New York before 1900 by Jacob Riis. For further information, an article (in German) discussing the museum can be found here
