Quite a racist poster when you look at it today, but wasn't considered like that when it was realized at the turn of the 20th century, in order to advertise the British movie "It Might Happen to You". Several white couples most likely belonging to the high society, are having a fancy dinner, and wearing toxedos, while they are being served by black waiters, and entertained by monkeys who play the orchestra. The anaolgy between the two latter ones is self explanatory.
