Original 1st printing 7&1/2 x 10&1/2" blank-reverse concert/performance flyer for 'Exodus Is", a multi-act show featuring the San Francisco Mime Troupe, Notes From the Underground and others, held at the Blind Lemon in Berkeley, CA on 12/27/1966.
 
 Artist unknown/not credited, thin flat stock flyer is in near mint to excellent (A-/B+ to B+) condition; there are a few well-camouflaged (mostly visible on the reverse side) handling creases here and there, but for the most part it is a fairly clean example of this oddball late-'66 SFMT artifact from Berkeley with a great op-art design.
