FDC bearing an affixed 15-cent stamp honoring Martin Luther King Jr., postmarked in Atlanta, Georgia, on January 13, 1979, two days before what would have been his 50th birthday, signed in black ink by a Civil Rights icon, "Rosa L. Parks, Montgomery, Ala. Bus Boycott, December 5, 1955-December 21, 1956," and signed in blue ballpoint by King's father, "M. L. King, Sr." In very fine condition. Encapsulated and graded by PSA/DNA as "NM-MT +8.5." A superb autographed piece honoring MLK's legacy.
