Sculptor William "Bill" Tarr created the large, untitled memorial that welcomes students to Martin Luther King Jr. Educational Campus in Manhattan. The steel block features quotations from King and famous phrases from the civil rights movement. It was designed to weather over time, changing in color and texture as it ages. The school was founded in 1975 and is now home to seven distinct high schools, each focusing on a different discipline, including law, technology, and the arts.
