An extremely rare handbill for 'San Francisco Rocks Boston,' a November 1969 concert at the Boston Music Hall featuring the Grateful Dead, Country Joe & The Fish and Pacific Gas and Electric (that likely was cancelled.) "The groups that rock The Coast will now rock Boston," notes the handbill, but no evidence can be found that this show actually took place. We know of only one other example of this ultra rarity having surfaced to date. 5 1/2" x 8 3/4"; in excellent condition with a bit of scuffing and handling/soft creasing (the areas that look like edge tears are only a bit of rubbed off ink.)
