If you view the enlargement of this image you will see remarkable detail in the foreground, including individual people, but also detail of buildings in the far distance in the image..

It seems that a significant part of Breger & Duval's business was printing on metal. That department and the scenery behind it is illustrated in this detail. In the far distance the Eiffel Tower is visible in the left upper corner of the image.

The very long and deep pressroom contains many steam-powered lithographic presses and some hand-presses. A very large steam engine is visible at the far end of the room. It appears that the belt drives powering the printing machines were in the basement for safety. The room appears to be very well lit with natural light from windows and skylights. The detail shown in the small engraving, with men operating various presses and no women visible, is remarkable.
