[Rock Island, IL: S.i., 1965]. Well-preserved poster for an NAACP demonstration in response to the events of "Bloody Sunday" in Selma, Alabama on March 7, 1965. The "peaceful demonstration," sponsored by the NAACP and students of Augustana College, was one of several demonstrations and "sympathy marches" held nationwide, on March 20, 1965. The poster, unadorned and hastily-printed, clearly outlines the aim of the demonstration - "To Protest: Racial Intolerance in Alabama and Mississippi AND The Beating of 3 White Ministers in Selma, Alabama" - followed by a powerful charge: "If you believe that God is our Father and all men are brothers, then YOU are urged to attend!" A superb poster, marking an important response to a watershed moment in the Civil Rights struggle. Not found in OCLC. Original poster, with text silkscreened in black and red on beige chipboard, measuring 36.25cm x 55.75cm (14.25" x 21 15/16"). Recto shows toning and dustiness, faint stress creasing, a few tiny tears, and a single pin-hole at upper margin; left edge shows the impact mark of either rotten fruit or vegetable matter, with resulting spatter across the poster; Very Good and sound.
