Original 1st printing 5&1/2 x 8&1/2" double-sided (map on reverse) concert handbill for the Sons of Champlin appearing with Phoenix and Freedom Highway at the Avenue Theatre in San Francisco, CA from 4/1-2/1968.

 Artist unknown/not credited, medium-thin flat index card stock handbill is in excellent (B+) condition; aside from a tiny pinch bend/indentation in the upper left margin (just above "Muggles"), a couple of tiny corner tip bumps and a minor amount of edge toning (mostly concentrated on the reverse (map) side), it is a very sharp example of this oddball little Sons concert artifact from a tiny theater in south San Francisco.

First one of these I have ever seen.
