U.S.A. (burnt/unburnt) is a 2011 installation by Paris-based artist Claire Fontaine (previously) constructed from thousands of green matches that were inserted into a wall at the Portland Institute for Contemporary Art as part art of “Evidence of Bricks” at the 2011 Time-Based Art Festival. Fontaine has made somewhat of a name for herself with her match installations and flaming geography, most recently completing a similar U.S.A. map at Queens Nails Gallery in San Francisco. Unlike the installation in Portland above, the Queens Nails artwork was actually set on fire, and while it may not have gone exactly as intended, the final post-flame artwork is impressive nonetheless.
