Original 1st printing (Maron Lithograph credit) 16&3/8 x 22" concert poster for  Buffalo Springfield appearing with Charles Lloyd and Turquoise at the Earl Warren Showgrounds in Santa Barbara, CA on 1/6/1968.

 Art by Frank Bettencourt, medium flat vellum stock poster is in used (B-/C+) condition; there is an extensive amount of moisture warping, corner/edge wear, tape stains/pulls/remnants, a series of hard horizontal creases traversing the image area, etc... the picture should tell the story with this example; HOWEVER.... this version (with the Maron credit) is next-to-impossible to find (apparently only 200 were printed), the late Jim Salzer did not even have one in his archives. A tough one, for sure... check out a great informative list of 1960's-era shows (including this one) held at the Earl Warren Showgrounds:
