Today Americans are celebrating the life of the noted civil rights leader, Dr. Martin Luther King, Jr. In 1983 President Reagan signed the holiday into law and it was first observed in 1986. The federal holiday marks the birth of Dr. King (January 15, 1929-April 4, 1968) and it is observed on the third Monday in January each year.
In 1978, the Postal Service initiated a long-running series of stamps highlighting Black Heritage with the issuance of a stamp honoring Harriet Tubman. The below stamp honoring Dr. King was the second in the series and was issued on January 13, 1979 (Scott 1771); it is a 15c multicolored, tagged, perf. 11 stamp depicting Dr. King and civil rights marchers.
Dr. King has also been featured on a stamp from the Celebrate the Century series (Scott 3188a; Sep 17, 1999).
