This contest is a beauty.

The City Reliquary Museum in Williamsburg on Thursday will hold a Miss Subways pageant, the first official one since the 1970s, where commuters will show off their skills to laud their favorite lines in hopes of claiming the crowning glory of a transit tiara.

Four judges — comedians Janeane Garofalo and Baratunde Thurston, performer the Reverend Jen Miller and NY1 host Roger Clark — will review 13 acts, including a drag performer, singers and stand-up artists. The pageant is a fund-raiser for the museum in Brooklyn and the Riders Alliance transit group.

Unlike its predecessors (fun fact: The pageant began in 1941), this year’s competition is open to all genders, identities and sizes. Courtesy Ilise Carter Ilise Carter is a sideshow performer who will be swallowing a sword for the Miss Subway pageant on Thursday.

But that doesn’t mean previous incarnations weren’t avant garde.

“It was very progressive for its time. It was the first integrated pageant in the country,” said Sarah Celentano, assistant director at the museum. “We’re really trying to continue this tradition of a progressive Miss Subways for 2017.”

Alex Low, a Riders Alliance member, pitched reviving the pageant as a fund-raiser for the group. He hopes the winner will be a subway ambassador for the riding public at a time when mass transit is leaving people hanging.

“This is the time to keep really putting people’s attention on the subway system,” he said.

The Miss Subways pageant starts at 7 p.m. at the City Reliquary, 370 Metropolitan Ave., Williamsburg.
