Voilà, pas mal de faute. Attention notamment à 'people' qui est toujours au singulier 
1-This document is the cover page of the newspaper "The New Yorker" (Dec. 22&29 1997)
2-We can deduce a lot from this document. Indeed, I can see 2 people, a man and a girl . There is a christmas tree on the left of this cover with many gifts at its feet, and there is one gift who is opened. In this gift there are many books. On one of these books, I can read " Fiction Issue ". On the top of this cover page, it is written "The New Yorker" and also the date: december 22nd & 29th 1997, and finally the price, which is $3.50. At the bottom, I can see a fireplace. So, as I was saying there are 2 people, a man and a girl. The girl is down the stairs with her left hand on the stair's rail. Although this girl is very pretty she's holding a gun on her second hand. The man is lying on the floor.
3-To my mind, I think these two pepole are a couple. I suppose the girl wanted a great gift, for example a ring or a gold necklace, but she didn't received what she excpected. She set with this man to see what it wanted but the man offered books and she kill him . Or they were fighting and the girl killed him. Futhermore, I suppose she killed him because he wanted to hit her or to rape her.
Plus, to my mind she regrets her action and she wants to escape the man's apartment. Or maybe on the contrary she will denounce herself to the police .
The purpose of this document is to advice us that we mustn't be fooled by appearances, a beauty can hide a monster.
4-To conclude, I like this cover, it makes me want to read it. At the last but not the least, we mustn't be fooled by appearances, the Devil can take the face of an angel.
Y'a peut être encore des fautes que je n'ai pas vues mais à cette heure
