Original 1st printing 22 x 28" concert poster for Santana appearing at the Long Beach (CA) Arena on 1/30/1977. 
Art by Randy Tuten and David Singer, image is featured in the Art of Rock book on page 371 (plate 4.117).
 
Medium glossy/coated index stock poster is in good/decent (B to B/B-) condition; there are numerous thin stress bends scattered throughout the image area, along with holes (tack and pin) in each of the four corners, light to moderate handling/surface wear throughout the piece, a series of tiny corner/edge dings scattered around the outer margin area and a few light splatter stains (and light toning) on the reverse.... definitely a bit on the used side, but still presentable.
 
Classic mid-'70's Santana image from Southern California.
