¡VIVA LA CAUSA! — Today marks the birthday of Cesar Chavez, the labor leader and civil rights activist. As the co-founder and leader of the National Farm Workers Association, later known as the United Farm Workers, Chavez sent this typed note of thanks to union supporter Virna M. Canson. It reads a bit like a form letter, but it’s still an interesting glimpse at early 1970s politics.
