From Etsy seller studiokmo:

four paper panels, each panel measures approximately three feet by four feet (overall dimensions, six feet in width x 8 feet in height) and exposes city blocks of brooklyn, manhattan, queens, and the bronx. the panels fit together like panes of a window and all four pieces must be sold as a set. image one would located in the lower left pane. image two located in the upper left pane. image three in the upper right pane and image four in the lower right pane. image five shows the delicacy of the pieces.
