Original 1st printing 11 x 18&3/8" concert poster for the Doors appearing with Iron Butterfly at the Berkeley Community Theatre in Berkeley, CA on 2/10/1968. 

 Art by Bob Masse (not credited), medium flat index stock poster is in very good (B/B+) condition; there are pin/tack holes in the upper left/right corners/margins (with small drag tears) and in the bottom center margin, along with a 4&1/2" diagonal bend along the lower right margin, a couple of soft stains under the "nt" of "Presents", a pair of add-on stickers ("KYA Presents" in the top center margin and "7:00-9:30" above "Theatre"), a couple of soft horizontal bends along the top margin and a quartet of fossilized masking tape remnants on the reverse side, otherwise fine.

 UNBELIEVABLY HARD-TO-FIND early 1968 Doors concert poster from Berkeley, you might assume that because of the location and the relative popularity of the headliner (not to mention the KILLER design) that there would be a lot more of these floating around, but they are next to IMPOSSIBLE to locate.
