Original 1st printing 14 x 20" concert poster for Electric Flag appearing with Mad River, the Fugs and the 13th Floor Elevators (*cancelled) at the Avalon Ballroom in San Francisco, CA from 2/2-4/1968.
 
 Art by Victor Moscoso, image is # 104 in the Family Dog/Avalon series.
 
 Medium smooth index stock poster is in near mint to excellent (A-/B+ to B+) condition; aside from a thin crescent-shaped crease along the top center margin, a few loose soft handling dings here and there and a pair of tiny light pulls on the reverse side, it is a mostly-clean example of this example of this always-popular early-'68 Avalon Moscoso poster with a decidedly gestural design.
