Black-and-white 11" x 14" photo signed in black and blue felt tip markers by Jefferson Airplane band members Grace Slick, Jorma Kaukonen, Jack Casady, Paul Kantner, Marty Balin, and Spencer Dryden. In fine condition. Accompanied by a full Letter of Authenticity from PSA/DNA (#U02811). A terrific, oversized photo with all six signatures from the San Francisco Bay based rock band. All six autographs are dark and set perfectly against the background, avoiding any overlapping and leaving space to see each member in the photo. A rare, fully signed piece of memorabilia that defined 1969's 'Summer of Love' from the band whose legacy can be seen at the Monterey Pop Music Festival, Woodstock, and so many more major musical events.
