Original 1st printing 15 x 21" concert poster for NYC avant-freak rockers the Fugs appearing with Kaleidoscope (featuring David Lindley) and the Family Tree (*not listed) at the Crystal Ballroom in Portland, OR on 5/3/1968. 

Art by San Andreas Fault (Tad Hunter), image is part of the short-lived "Crystal Dog" series (sometimes considered to be a minor extension of the Family Dog/Portland series).

 Medium flat vellum stock poster is in good/decent (B/B-) condition; the one major issue is a 1 x 6" area of brown glue residue along the lower right margin (from a previously-placed sticker); besides that, there is a slight diagonal bend along the upper right margin, a small 1/2" bend in the bottom left corner, a couple of minor handling dings here and there and a touch of edge toning, otherwise fine. 

One of the best-looking Crystal Dog images, this one has always been one of the harder-to-find posters in the series. Check out an EXTENSIVE gig list/history of the Crystal Ballroom during the late '60's HERE:
