The quote and image represent Gatsby’s obsession for Daisy and that he would do nearly anything to get her to leave Tom and live with him. The lack of people in the background represents the fact that Gatsby fired all of his existing butlers and canceled his parties after finally making contact with Daisy. It also represents that Gatsby had always used the parties as a way to find Daisy, and finally make contact after the war.
This
is the quote that shows what Gatsby had to do to make the money that he has. It shows that he had been working since his days with Dan Cody on the ship. He uses inheritance to hide that he made his money in shady/ illegal ways. The image also shows his loneliness after firing his servants and cancelling the parties, and his failure in trying to get Daisy to leave Tom. In the end, it was just Gatsby and his money.
