Concert poster February 22, 1983 at the Corte Madera Rec Center, Corte Madera, CA. 13.25" x 20" Alton Kelley provided the artwork for a numbered series of nine posters produced in 1982 and 1983, plus at least five other posters not numbered. on heavy glossy stock (the poster was printed on the non-glossy side). This is a nice series for collectors (art by one of the "big 5" artists, not too many in the series, and no authorized reprints were made). So far as I know, only two of the posters had postcards printed with them, and only one with poster-image tickets. All of them should be reasonably available (check the poster auctions) but the #7 (Godzilla image) is likely to be pricey. This poster is available at Wolfgang's Vault for $255.
From Wikipedia: The Dinosaurs, formed in 1982, was a Bay Area supergroup to emerge from the psychedelic music era of San Francisco. The core group consisted of Peter Albin of Big Brother and the Holding Company, John Cipollina of Quicksilver Messenger Service, Spencer Dryden of Jefferson Airplane, Robert Hunter of the Grateful Dead, Barry Melton of Country Joe and The Fish and keyboardist Merl Saunders from the Saunders-Garcia Band. Over time Papa John Creach of Hot Tuna, Jack Casady of Jefferson Airplane, Nicky Hopkins,Dave Getz, Country Joe McDonald and other prominent San Francisco musicians would guest star with the group. In the 1990s David LaFlamme of It's a Beautiful Day and Jerry Miller of Moby Grape also toured with this group.
The Dinosaurs became active in 1982, with Albin, Dryden, Cipollina, Melton, and Hunter at its center. Hunter would later leave the group (in 1985) before the end of its "classic" run, though he would return to record a track for their only album, released in 1988. By 1987, Merl Saunders had more or less taken Hunter's place in the band. The original group presumably ran its course up through 1989, at which point the group broke up (John Cippolina died just two weeks after the band's final concert, during which he had to sit in a wheelchair due to health issues). Unfortunately, the rest of the band's history (up through the 1990s and beyond) is poorly documented. In fact, their entire history is poorly documented, save for concerts on the audio archive. In 1988, the band released its only studio album, Dinosaurs. In 2005 the band released a retrospective album on the Evangeline label, entitled Friends of Extinction.
