Original 1st printing 13&3/8 x 21&3/4" concert poster for Howlin' Wolf appearing with Country Joe & the Fish and the Loading Zone at the Fillmore Auditorium in San Francisco, CA from 4/14-16/1967.
 
 Art by Peter Bailey, image is # 59 in the Bill Graham/Fillmore series.
 
 Medium flat vellum stock poster is in good to very good (B to B/B+) condition; there are staple holes in all four corners and in the top center margin, along with a thin strip of discoloration/toning stretching across the top margin, a slight horizontal tape residue shadow in the upper left margin (old price tag), a few stray surface smudges and soft handling dings here and there, a hint of edge/corner-tip wear, a subtle horizontal wave to the paper and a set of tape pulls/remnants (a couple with tiny bits of paper stuck to them) on the reverse, otherwise OK.

 Decent-looking semi-used example of this very pretty 1967 Fillmore poster.
