The LeRoy family gathered Wednesday at their restaurant, Tavern on the Green, to dedicate Maximilian’s Pavilion, where “Central Park: A Promise of Spring,” a new 162-foot mural, more than two years in the making, has just been installed.

The room, which will primarily be used for banquet events, is named after the famous restaurateur Warner LeRoy’s only son, Maximilian LeRoy, who died in 2005 at the age of 30 in a motorcycle accident in Los Angeles, Calif.

Before moving to Los Angeles, Maximilian worked at Tavern, where he had also grown up; it was the location of his birthdays, his bar mitzvah, countless family events, and countless parties he threw.

“He was a rock star and gorgeous: a cross between James Dean, Billy Zane, and George Hamilton,” his sister, Carolyn Plum LeRoy, said. “He was well-known for his hugs.”

In a tiny rendering, smaller than the size of swallows and red robins shown elsewhere in this 360-degree mural, Maximilian appears in character, with his arms around the Tavern’s creators, also deceased: his father, who died in 2001, and the designer of the Tavern on the Green and the Russian Tea Room, Jeffrey Higginbottom, who died in 2006. They are seated in the Crystal Room, sipping martinis. Warner is holding a cigar.

“My father would love the flowers; gardens were one of his passions,” the daughter of Warner whom he appointed to run Tavern on the Green, Jennifer Oz LeRoy, said, standing next to the spot where the threesome appears.

Higginbottom’s father, Russell Higginbottom, and sister, Andrea, agreed the rendering captures Jeffrey well. “Jeffrey had a loud laugh and he loved martinis. Warner couldn’t keep up with him,” Mr. Higginbottom, who is 96, said.

The picture of the three men is a quiet sentimental moment in an artwork bursting with the splendor of Central Park.

Jennifer, who likes to paint skies, noted the depiction of the Dakota, where she grew up, and the section showing Bethesda Terrace.

“Hopefully it will get people out into the park,” she said.

In formal remarks, mural artist Ron Genereux, whose company, Artgroove, has painted murals for hotels, casinos, restaurants, and private homes, compared his job as a painter to those of Frederick Law Olmsted and Calvert Vaux who designed the park. “Central Park truly is the most important work of art of the 19th century,” Mr. Genereux said.

After the reception, Carolyn walked this reporter through the gallery of family photographs at the restaurant’s entrance, including one of the Crystal Room decorated for her wedding. Then it was off to dinner with her mother, Kay, sister, Jennifer, Mr. Genereux, and his collaborator, Hank Richards.

“I like the lobster bisque,” Carolyn said.
