Original 1st printing 14 x 19&1/4" concert poster for Big Brother & the Holding Company (featuring Janis Joplin)*-canceled), appearing with H.P. Lovecraft and the Clara Ward Singers at the Carousel Ballroom In San Francisco, CA from 5/24-26/1968.
Art by "Crazy Arab", image is featured in the Art of Rock book on page 180 (plate 2.164). This is one of the "blocked" versions (see below).
Medium flat index stock poster is in near mint to excellent (A-/B+ to B+) condition; aside from a touch of toning, one or two stray tiny edge dings and some VERY well-hidden handling dings, it is an absolutely KILLER example of this oft-requested Carousel Ballroom poster. BIZARRE design on this one!
*Big Brother backed out of the show and a number of posters (such as this example) were distributed with the band's name crossed out with different colored magic markers. They were replaced on the bill by Mad River (thanks to Ross for the info!)
