I confess that this might have come from later than the 70s, but looking at it that doesn’t seem very likely. Those “drinkups”… Thanks to Dog & Hat for the tip-off!
Coffee is a brewed drink prepared from roasted coffee beans, the seeds of berries from certain Coffea species. The genus Coffea is native to tropical Africa (specifically having its origin in Ethiopia and Sudan) and Madagascar, Comoros, Mauritius, and Réunion in the Indian Ocean.
