Original 1st printing 8&1/2 x 11" concert flyer for Hot Tuna (featuring Jorma Kaukonen and Jack Casady of Jefferson Airplane (also Marty Balin at this show) appearing with the Amboy Dukes and the Flamin' Groovies at the "New Old" Fillmore Auditorium in San Francisco, CA from 4/10-11/1970.
 
 Art by "Grace", thin flat stock flyer is in excellent (B+) condition; there are a couple of tiny "mouse bite" nips along the left margin, along with a few tiny edge/corner-tip creases, a few soft handling dings here and there and an odd vertical printing anomaly (looks like light streaking/splotching just to the left of the center of the image area), otherwise fine.

 VERY UNUSUAL oddball early-1970 concert artifact from the brief period that the original Fillmore was managed/booked by the Flamin' Groovies management.
