Tribune caption that was stapled to the photo, Nov. 8, 1970-- "People in crowd shouted abuse, gestured and hurled aobjects which dented vehicles in presidential caravan, broke bus windows." Handwritten on the back of the photo, "Presidential Limosine is held up in center left.. Secret Service follow up car in center, as militants throw debris at party and wave banners and vocalize against Nixon. This is parking lot at San Jose auditorium. Pix taken from press bus." Photo shows a huge crowd standing on either side of a small pathway created for a line of cars to drive through. Poor quality photograph.
