An extremely rare signed copy of the Jefferson Airplane's debut album signed by original singer Signe Anderson, Marty Balin, Paul Kantner, Jorma Kaukonen, Jack Casady, and Spencer Dryden. Anderson, Kantner, and Dryden sign their first names, the others sign first and last names. This is one of only two sets of Airplane autographs I've ever seen with Signe Andeson. Signatures are darker than they appear in photos. NM-.
