Original 1st printing (Maron Lithograph credit) and official promoter-issued 2nd printing (no 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-thin flat vellum stock posters are both in near mint to excellent (A- to A-/B+) condition; aside from a couple of miniscule edge dings (slightly more pronounced on the reprint) and light handling dings on both, a series of light fingerprint smudges on the gold pass of ink on the reprint and a couple of tiny pin-prick surface spots on the 1st printing, they are in REALLY nice shape. The difference in the two printings is quite striking when they are side-by-side- the image is MUCH clearer on the original. 

 The 1st printing version (with the Maron credit- see close-ups) is quite difficult to find (apparently only 200 were printed); according to the consignor, Jim Salzer apparently 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:
