Forty years later, only a few CETA public art projects remain. Most visible among these are two ceramic murals in Brooklyn’s Clark Street subway station. (The artists were Johan Selenraad and Alan Samalin; realization in ceramic was by Joe Stallone). Four successful and popular murals installed at the World Trade Center were destroyed in both the February 26, 1993 and the September 11, 2001 attacks. The Archives of the City of New York houses historical materials from and about the project.
