Chavez (L) is accompanied by San Francisco Supervisor Bob Gonzales (R) as they march in a picket line outside a supermarket in San Francisco on March 22, 1979. The farmworkers were boycotting Chiquita bananas, which were produced by a firm that owns one of the nation’s largest iceberg lettuce producers, the UFW’s chief target in a strike. Led by Chavez, some 250 picketers paraded in front of the store. UPI File Photo
