Sweet Caporal Cigarette Button 1896

Got this old button (1 inch) with the old Nicaraguan flag on it. I thought it was from Nicaragua but on back it says 'Sweet Caporal Cigarette' and 'Button made by Whitehead and Hoag Newark NJ' and the date is 1896. I think this was a popular cigarette in the day in United States. I know some tobacco companies did cards and buttons for promotion. It is in pretty good shape.
