Original 1st printing 5&1/2 x 8&1/2" blank-reverse concert handbill for Quicksilver Messenger Service appearing with Ten Years After, Smith and Eric Mercury Birthrite at the Olympic Auditorium in Los Angeles, CA on 3/21/1970.

 Designer unknown (show was promoted by Bill Graham's "Shady Productions"), thin flat stock handbill is in very good to excellent (B/B+ to B+) condition; aside from a few very well-camouflaged thin bends, a tiny stain/bend in the upper right corner tip, a few light handling creases and a stray pin-prick surface spot or two hiding within the image area, it is a great-looking example of this semi-uncommon oddball QMS concert artifact from Los Angeles.
