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 index stock poster is in excellent (B+) condition; aside from a few soft handling dings, a thin bend in the upper left margin, a tiny nip in the lower right margin and a bit of light inking along the left/right margins (*a common trait with this poster), it is a SUPERB-looking example of this semi-uncommon early-'69 poster from the Jim Salzer Presents series.
