Description

AOR-2.214 First print original poster advertising a show on April 6th 1968 at The Earl Warren Fair Grounds Santa Barbara, CA.
Featuring Electric Flag, Steppenwolf and Traffic.
A little unsure how to grade this poster as it is near mint except for some jagged edges at the top and bottom (see pics) probably either from the printing or cutting process.
Poster is signed by Frank Bettencourt.
