Original 1st printing 12 x 18&7/8" concert poster for Jefferson Airplane appearing with Three Dog Night, It's A Beautiful Day and Lee Michaels at the Swing Auditorium in San Bernadino, CA on 4/26/1969.

 Art by C. Boulton, thin glossy-coated vellum stock poster is in used (B-) condition; there are pronounced horizontal/vertical creases/folds, along with large tape marks in the top/bottom/left/right center margins, a 1&1/2" tear in the bottom center margin, a moderate amount of handling wear/stress creasing, a bit of light moisture staining along the top/bottom margin areas, tack holes and wear in all four corners... definitely a well-traveled artifact.

Conditional issues aside, still a VERY scarce/uncommon 1969 Jefferson Airplane concert artifact with a KILLER design. Read more about this show (and others) held at the Swing Auditorium from 1967-1969 HERE:
