Original 1st printing 3 x 4&1/2" concert ticket for Sopwith Camel appearing with the Knack and Grass Roots at the Earl Warren Showgrounds in Santa Barbara, CA on 3/11/1967. 

Art by John Cushing, medium-thin index card stock ticket is in good to very good (B to B/B+) condition; aside from a couple of tiny staple holes and a tiny pressure wedge just above "Presents" and a moderate degree of toning, it is a fine example of this neat 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:
