 Design by San Andreas Fault (Tad Hunter/Paisley Penguin Studios), thin flat stock handbill is in excellent (B+) condition; there are a flattened series of horizontal/vertical folds (5-6 total), a few light handling dings/soft creases/stress bends here and there and a couple of light corner bends, otherwise it is a fine-looking example of this oddball Phrenology-themed flyer from the legendary Keystone Korner.
