Original 1st printing 5 x 7" blank-reverse concert handbill for Country Joe & the Fish appearing with the Sons of Champlin and the Mystery Trend at Longshoreman's Hall in San Francisco, CA on 6/30/1967.
 
 Artist unknown (credit too small to make out), medium flat index stock handbill is in good to very good (B to B/B+) condition; there is a decent-sized surface scuff on the second "o" of "Longshoreman's", along with a bit of minor handling/corner-tip wear, a few tiny bends here and there, a bit of surface rubbing in the upper right quadrant, light toning and a small sticker with the promoter's contact information on the reverse (see photo), otherwise fine.
 
 Nifty little mid-'67 CJF concert handbill with a sweet design. First one of these I have seen with the promoter label on the reverse.
