First it was The Decision to join the Heat and then the homecoming with the Cavaliers. Will the kingdom in New York City be next for LeBron James?

A New York City marketing company, NYC Ads Co., is trying to do its part to make it so. It laid down a challenge to the Cavaliers star in a big way late Thursday night with a billboard across the street from Madison Square Garden.

It lobbies for James to prove he’s the king of New York as he claims by coming to fix the Knicks. James and the Cavaliers return to the Garden on April 9 to face the Knicks, who will miss the playoffs for the fifth straight year.

The blue sign, which stretches vertically along the side of a building, has James and the No. 23 on the back of a white Knicks jersey at the top and reads “King of New York? Prove it. #KingJamesNYC18.”

In an Instagram post with a video of the billboard on the NYC Ads Co. account it reads: “If you talk the talk you gotta walk the walk. You want to be considered the goat? Legend? Icon? I think the best way to solidify all that is winning a chip in NY a place that hasn’t seen it in 40 years the Mecca of basketball.”

James declared himself the king of New York in an Instagram post after riding the subway and dispatching the Knicks 104-101 at the Garden, thanks to a 43-25 fourth quarter back in November. The claim irked Knicks center Enes Kanter. James finished with 23 points, 12 assists and nine rebounds.

The four-time MVP can opt out of his contract with the Cavaliers this summer. Cleveland, where he won an NBA title in 2016, is currently 49-30 and trying to hold off the 76ers for the third seed in the East.
