Original 1st printing 21&1/8 x 16&1/4" concert poster for Lee Michaels appearing with Elvin Bishop (Group) and Paul Butterfield (Blues Band) at the Cal Expo Fairgrounds in Sacramento (CA) Memorial Auditorium on 3/13/1970. (*also a showing of the Cream Final Performance at the Royal Albert Hall film)
 
 Design by Ray Hidalgo, medium-thin semi-glossy textured stock poster is in very good (B/B+) condition; there is a bit of handling wear/creasing and a trace of moisture rippling throughout the poster, along with a small 1&1/2" hard diagonal bend in the lower right corner, a couple of VERY thin vertical roll creases and tiny horizontal stress bends hiding within the image area, a tiny pin-prick spot between "Michaels" and "Elvin" and a few stains with a bit of pen scratch/writing on the reverse (show lineup in black flair pen), otherwise fine.

 Very nice-looking example of this patriotically-themed early-1970 concert artifact from Northern California.
