This picture represents an hotel which is reserved for black people. The scene took place in the USA, around the 20 century. This hotel is reserved for black people, because of segregation law, that is to say the white and the black people were seperated. 
J'ai pas grand chose à dire :-/ Dis-moi ce que tu veux que je te traduise, et je le ferais! :-P
It's a black and white photography. We can see an hotel " the Hotel Clark" which is reserved for black and colored people. It might happen in the USA or in South Africa maybe during the Apartheid. In the bottom of the picture we can see 3 black men, they seems to be leaving the hotel. We can also see a policeman who is controlling one of the black man.

Voila après je vois pas trop ce que tu peux rajouter :)
