Original 1st printing 7&1/2 x 11" concert flyer for Quicksilver Messenger Service appearing at the Continental Showcase in Houston, TX from on 9/6/1970.

 Designer unknown (credit is too small to make out), lettering by Rick Griffin, extra-thin silver-coated reflective stock handbill is in GORGEOUS near- mint (A-) condition; just a couple of nearly-invisible pinch dings hiding within the image area and a tiny crease in the top left corner tip, otherwise it is as clean/sharp an example as you can hope to find.

 REALLY cool-looking late-1970 oddball QMS concert handbill from Texas.
