Original 1st printing 8&1/2 x 11" concert flyer for the 5/21/1968 edition of the weekly "Tuesday Night Jam" (A/K/A "Carousel Rock Jam"), held at the Carousel Ballroom in San Francisco, CA.
Design by Alton Kelley/Carousel Crew (a variation on the "Sore Thumb" image from 3/14), the corresponding Stanley Mouse image ("Tuesday Night Pig Jam") is featured in the Art of Rock on page 181 (plate 2.170). This version lists participants Jerry Garcia and Mickey Hart (Grateful Dead), Jorma Kaukonen and Jack Casady (Jefferson Airplane), Elvin Bishop, Steve Miller, "and others".
Thin flat stock flyer is in sparkling mint/near mint (A/A- to A-) condition; aside from a nearly-invisible handling ding or two, this example is as crisp/clean as they come... a GORGEOUS specimen.
A VERY, VERY scarce mid-week Carousel item featuring an INCREDIBLE "pick up" band... there is supposedly even a tape out there from this event (not on the LMA, unfortunately).
