Cooper also combines multiple perspectives in his drawings, some exaggerated, some rotated. This approach gives viewers the sense that they could “walk right into” the murals from any angle and emphasizes dramatically sloped architecture and landscapes. He uses a method of memory drawing that presents details based on their remembered significance—with the most important parts appearing the largest.

The murals show King County from West to East, beginning in the West Corridor of the courthouse lobby, passing through its central rotunda, and extending down its East Corridor. Among the many landmarks, locations, and histories included are Lake Union; 1909’s Alaska-Yukon-Pacific Exposition; the mining, logging, and fishing industries; musical figures Quincy Jones and Kurt Cobain; Snoqualmie Valley and Falls; women's rights suffragettes; Civil Rights protesters; and Seattle’s namesake, Chief Sealth. From panel to panel, the murals focus on themes of wealth—both its creation and its distribution.

Gregoire Picher assisted Cooper with the figures in the murals and Patricia Clark contributed to their geographic and architectural features.

Based in Pittsburgh, PA, Cooper primarily makes panoramic civic murals. Some of his other large murals can be seen in Philadelphia, San Francisco, Frankfurt, New York City, and Rome.
