Original 1st printing 11 x 16&1/2" concert poster for Sweetwater appearing with the Evergreen Blues Band and Strange Brew at the Oxnard (CA) Recreation Center on 2/28/1969.

 

 Art by (and SIGNED in black pen by) Frank Bettencourt, medium-thin flat vellum stock poster is in near mint to excellent (A-/B+ to B+) condition; aside from a few soft handling dings and a bit of light inking along the left/right margins, it is a SUPERB-looking example of this semi-uncommon early-'69 poster from the Jim Salzer Presents series.
