Childe Hassam was an eyewitness to the World's Columbian Exposition in Chicago.

Hassam "added backgrounds and figures to a group of existing architectural drawings by other artists which were then reproduced as a series of chromolithographs entitled Gems of the White City." (Source of quote below.)
The perspective structure of the buildings is carefully measured. The vertical lines are executed with white gouache over a light gray base color using the paint in a ruling pen.
The style or mindset seems quite different from the chaotic and casual approach to the figures and distant areas.
