Original 1st printing 10&7/8 x 17" concert poster for the Jerry Garcia and Friends (A/K/A Legion of Mary, featuring Merl Saunders, Martin Fierro, Ron Tutt and John Kahn) appearing at the EMU Ballroom in Eugene, OR on 12/15/1975.

 Designer unknown/not credited, thin flat index stock poster is in excellent (B+) condition; there is  a small diagonal bend and a bit of light surface smudging in the bottom right corner tip, along with a few light handling dings scattered throughout the poster and a couple of slightly soft corner-tip bends, but overall it is in really nice shape.

 SUPER-SCARCE Legion of Mary concert poster from Eugene, this is only the second example I have seen. Check out the LOM's superb cover of Jr. Walker's "Shotgun" (released on "Garcia Live Vol. 3") from the show HERE;
