Original 1st printing 11 x 17" (slightly trimmed appx. 1/8" along the right margin) concert poster for Led Zeppelin and Jethro Tull appearing together at the Swing Auditorium in San Bernadino, CA on 8/8/1969.

 Art by Sokolis, thin flat stock poster is in good to very good (B to B/B+) condition; aside from the previously-mentioned right edge trimming, there is a flattened horizontal center crease and a couple of minuscule edge dings along the left margin, otherwise it is a KILLER example of this fairly uncommon mid-1969 Zeppelin/Tull concert artifact from a VERY early Southern California appearance.
