SEALED, Joan Baez - Diamonds & Rust, 8-Track Cartridge, Quadraphonic, US, 1975

This is the original 1975 Quadraphonic first edition, not a later reissue. Finding a copy that remains factory-sealed after more than 50 years is exceptionally rare. The shrink wrap is intact, and the "Printed in U.S.A." marking is clearly visible on the side.
