But why open a day before Mr. West’s “Saint Pablo” tour, two days before the V.M.A.s?

It seemed sheer whim, Mr. Blum indicated. Mr. West wanted an art world unveiling, a piece that members of his creative collective, DONDA, said had taken four months of animation modeling, 3-D scanning, stylist consulting, Instagram searches. The result was startlingly accurate. Each animatronic body was hand-sculpted down to the freckles and hair (human!), all applied by hand, piece-by-piece, and none more ghoulish than Mr. Cosby’s freckles or Mr. Trump’s fleshy behind. Since Mr. West’s “Graduation” album cover was crafted by Takashi Murakami, a client of Blum & Poe, the gallery was a natural fit.

When asked about the multimillion price point, Mr. Blum laughed. It is on sale — “for the right buyer,” he said. When you tally the materials needed, labor and Mr. West’s name, the $4 million price tag doesn’t seem so outlandish. “I would project a figure about that,” Mr. Blum said.

“To be honest, we did it for the sake of doing it,” Mr. Blum continued. “The show and project were not done with price or sale in mind. But I would act upon it as every other piece of art I handle.”

The show lasted one weekend. Like the man himself, flighty and busy, Mr. West showed up for a few minutes via an onscreen avatar on Friday night. That’s it.

“Kanye is Kanye,” said his trainer of three years, Joe Bouraima, a French national whom Mr. West had helped to secure a visa after a fortuitous 2013 meeting in Paris. Ever since, the hulking Mr. Bouraima has been on and off tour with the artist for months, training daily while working on “Famous.” Not once did Mr. West mention the project. And then, just like that, the mercurial Mr. West decided to stage the pop-up show in Los Angeles — and then it was gone. Poof. But to where?
