Paul Stookey, Mary Travers, and Peter Yarrow signed In the Wind vinyl, authenticated by PSA. This is a desirable piece for collectors of Peter, Paul and Mary material, combining all three member autographs on one vinyl item tied to a classic folk release. The PSA authentication provides added collector confidence, and the signed album format makes it a strong display piece for music memorabilia collections focused on 1960s artists and group-signed items.
