S.N.A.C.K. - Students Need Athletics, Culture, And Kicks, was a project of Bill Graham to give back to the San Francisco community. When city budget cuts meant an end to all extracurricular activities in schools, he staged a concert with 11 performers and over 50 guest celebrities. 50,000 attendees at S.N.A.C.K. at Kezar Stadium raised enough money to keep extracurricular activities in San Francisco schools going for one year.
Concert promoters created handbill versions of many of their posters and used them as sidewalk handouts and dashboard fliers to promote upcoming shows. Many of the handbills are double-sided, with poster art on one side and a calendar of upcoming shows on the other. These handbills represent an important element of rock concert history because they were hands-on marketing tools that united promoter and patron.
