Original 1st printing 10&7/8 x 14&3/4" concert poster for fthe Grateful Dead appearing with the Powers of Evil, OM and Hemp Plant at the Continental Ballroom (auditorium) in Santa Clara, CA on 10/14/1967.

 Design by Lee Cannon, medium-thin textured index stock poster is in near mint (A- to A-/B+) condition; just a few nearly-invisible handling dings hiding within the image area and a whisper of toning on the reverse side, otherwise it is an absolutely GORGEOUS example of this late-'67 Grateful Dead oddball from the South Bay.
