Portraits & Observations: Emily Prince documents the cost of war

In her San Francisco studio, artist Emily Prince quietly continues a work-in-progress, her vast memorial to U.S. troops whose lives were lost in Operations Iraqi Freedom and Enduring Freedom. The artwork she’s created, completely by hand, consists of thousands of individual, wallet-size portraits, finely drawn in graphite, that, when arranged on a wall, create a very large map of America.
