Charming music-themed 1986 first day cover, boldly signed with his name alone in blue felt-tip marker in the 1980s. In very good condition. Multiple Grammy-winning singer, guitarist, banjoist, and activist Peter Seeger, who was a member of the Weavers in the 1950s before embarking upon his solo career, composed a number of folk standards, including "If I Had a Hammer", "Turn! Turn! Turn" and "Where Have All the Flowers Gone?" Not a common autograph!
