The United Farm Workers Union were regularly in front of the Berkeley CO-OP on Shattuck Ave. I happily wore their buttons: when I was younger because the buttons looked so cool, when I was older because I supported their cause.
This is the kind of thing that makes me proud to be from Berkeley. That regular trips to the supermarket were infused with a radical awareness of where the food we were eating came from, and reminders of exactly who were bringing that food to our tables.
I still love this button.
