A famed so-called “earth artist” who backs Beto O’Rourke used sand, gravel and rocks to create a portrait of the Democratic presidential candidate that can be seen by thousands of passengers using the nearby Austin-Bergstrom International Airport.

The massive artwork of O’Rourke — which takes up almost two football fields — was the creation of Stan Herd of Lawrence, Kansas, according to an Austin TV station KVUE.

“We’re trying to tell the story of this amazing man from Texas making a difference in the national climate,” Herd told the station.

“It’s kind of bringing community into an art effort, and that’s the artist’s dream.”

Herd said materials for the project — earth, gravel, sand, mulch and rock to add color and texture — came from the site, about a mile and a half from the Texas airport.

“We try to get close to an airport to guarantee a closer audience,” said Herd, who has been creating art for four decades using organic materials.

For his portrait of the former Texas lawmaker, he used another local product.

“Pecans are a big product in Texas,” he said, referring to O’Rourke’s eyes. “It’s a nice brown color.”
