Original 1st printing (Maron Lithograph credit) 4&1/8 x 6&1/2" unused concert ticket (# 2585) for Buffalo Springfield (with Stephen Stills and Neil Young) 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 index stock ticket is in excellent (B+) condition; there is a small diagonal pressure crease/bend and a tiny corner-tip split in the lower left corner, along with a couple of tiny pin-prick rust spots in the left margin, a well-camouflaged handling ding or two and a couple of soft/rounded corner tips, otherwise fine. Neat little oddball early-'68 Springfield artifact. Check out a great informative list of 1960's-era shows (including this one) held at the Earl Warren Showgrounds:
