Answer:
The background of this photo helps its credability. The people in the background are posing for the photo, with one wearing a hat, while the others are wearing what we would consider modern-day formal wear. This would make sense because the photo was taken at night, meaning that the men are dressed in their nice clothes for a night in New York City. The wall in the foreground has light stains and disformed trash cans near it. Also, we can see that the light used for the flash makes a rough circle. We can see a young lady in the far left corner, looking at the men. She appers to be in a nightdress, further proving that this photo was taken at night and that this photo is crediable.
