The stamp series, named “Forever,” is sold at post offices nationwide and features a color-toned black-and-white photograph taken in the early 1960s of a singing Seeger in profile, playing his five-string banjo.
“It is an honor to see a photo of my father that I took some 60 years ago become this wonderful stamp forever,” his son, Dan Seeger, said in a statement.
The banjo-playing folk singer and activist handled his correspondence mainly with handwritten letters, according to the son.
“And I can imagine him smiling and of course appreciating this great honor because he trusted US Mail with its simplicity and honesty.”
Pete Seeger died in 2014 at the age of 94. He is known, among other things, for having popularized the protest song “We Shall Overcome” and having written, or co-written, songs such as “If I Had a Hammer”, “Turn, Turn, Turn” and “Where Have All the Flowers Gone”.
Seeger was known for his left-wing sympathies and was blacklisted by the Committee on Un-American Activities in the 1950s.
