A memorial sign at Graball Landing, the spot where Emmett Till's body was pulled from the Tallahatchie River just outside of Glendora, Miss., is photographed Monday, July 24, 2023. President Joe Biden created a national monument honoring Till, the Black teenager from Chicago who was abducted, tortured and killed in 1955 in Mississippi, and his mother Mamie Till-Mobley. Altogether, the Till national monument will include 5.7 acres of land and two historic buildings. The Mississippi sites are Graball Landing and the Tallahatchie County Second District Courthouse, where Emmett’s killers were tried. (AP Photo/Rogelio V. Solis)
