Original 1st printing 8&1/2 x 11" concert flyer for the Steve Miller (Blues) Band appearing at the Matrix in San Francisco, CA from 4/21-23/1967.
Art by Leidenthal, extra-thin flat stock flyer (*blue stock version) is in fantastic near mint (A-) condition; aside from a couple of tiny bends in the upper left/right corners and a nearly-invisible soft handling ding or two hiding within the image area, this example can't be beat.
REALLY cool-looking early-'67 Matrix flyer with a great design.
