Coca-Cola pioneered the use of coupons to advertise its beverage to the public in the late 1880s.  Earliest coupons offer complimentary glass servings of Coca-Cola at the soda fountains in Atlanta.  One of my favorite coupons in my collection is the Lillian Nordica advertising card with coupon from 1905.

1905 - Nordica Ad Card and Free Glass of Coke Coupon

The coupon states: "This card entitles you to a glass of Coca-Cola at the fountain of any dispenser of genuine Coca-Cola."
