Original 1st printing 3&7/8 x 5&7/8" unused concert ticket (# 2485) for Traffic (featuring Steve Winwood) appearing with the Electric Flag and Steppenwolf at the Earl Warren Showgrounds in Santa Barbara, CA on 4/6/1968.
 

 Art by Frank Bettencourt, image (poster) is featured in the Art of Rock book on page 267 (plate 3.43) and is part of the Jim Salzer Presents series. 
 
 Medium-thin index card stock ticket is in near mint to excellent (A-/B+ to B+) condition; aside from a few soft handling dings here and there and a trace amount of edge toning, it is a superb example of this bright little ticket from the Salzer series; check out a great informative list of 1960's-era shows (including this one) held at the Earl Warren Showgrounds HERE:
