A giant pop-up book unfolds at LA’s Central Library

A pop-up book that’s seeking to break the world record for size has unfolded at the Central Library in downtown Los Angeles.

The art piece is 31 feet wide, more than 11 feet tall, and weighs in at 1,800 pounds.

Luceros y Penumbras, which roughly translates to “starlight and shadows,” is rooted in L.A. artist Daniel González’s experience visiting the library and his family in Mexico as a child.

“It's a knowledge tree that's been shaped by all these different things that I've learned at the library, about myself, about the city I grew up in, [and] about the town where my family's from,” González said.

The nonprofit Library Foundation of Los Angeles collaborated with the library to commission the piece as part of the Central Library’s centennial celebration.

The project is inspired, in part, by the library’s Toy Movable collection, an archive of more than 2,000 pop-up books.

“Normal pop-up books … they seem so simple, but something amazing pops out when you open the page,” said Todd Lerew, the foundation’s director of special projects. “That sort of childlike wonder that you feel that's persistent, even as an adult, is something that was really important to capture and dial up to 11 with this project.”

The origin of 'Luceros'

The foundation asked González in June 2025 to create a book that told the story of his personal relationship with the library. As González pondered questions including  ”What did the library do for me as a young person?" and "Why was I so attracted to it?" he thought about how knowledge was passed down in his family through the generations.

His grandmother told him stories about the stars above her farm near Teúl, Zacatecas, in Mexico. She said those that emerged at dawn — luceros — were among the most special because they signaled the start of a new day.

“ I looked at those stars … and the histories that my grandparents were sharing with me as these guiding lights,” González said. “Just like the library is a guiding light for many people.”

Daniel González's maternal grandmother, Isabel Gómez, told him stories about the creatures that lived near her farm, including owls, that could teach healing.

González grew up blocks away from the Benjamin Franklin Library in Boyle Heights.

“ I spent summers there because it was literally the coolest place to be,” González said. “It just gave me the opportunity to explore anything that I had an interest in.”

Later, he’d visit the Central Library during a middle school field trip and return on the bus to wander the stacks and ask the staff questions.

“ I'm really lucky that I met the people that nurtured that curiosity,” González said.

From sketches to ‘paper engineering’

First, González sketched the images, carved them into linoleum, printed them with ink and digitized them to add color and other details.

Matthew Reinhart, children’s book author, illustrator and “paper engineer,” was tasked with translating the images into three dimensions.

“ My job is really making mistakes,” Reinhart said. “Making mistakes, figuring out where they are and solving them and — of course — making them look good.”

The construction and the fabrication of the book took the work of more than 30 people over a series of months. At least a dozen people using giant poles capped with cushions turn the pages.

Luceros y Penumbras is four pages that open to create two scenes — one of the Central Library building and another of a sprawling tree with an I Spy-like collection of creatures and images throughout. The featured pages will change throughout the exhibition, which is open until mid-November.

There are at least a dozen different symbols throughout “Luceros y Penumbras."

The sea turtle at the base of the tree is a reference both to the creatures that live in the San Gabriel River and to the original inhabitants of the L.A. basin. The Gabrielino-Tongva Tribe tells a story that connects the region’s earthquakes to the turtles.

“When we think of sea turtles, we think of these faraway places where they live, like tropical places,” González said. “But they exist here and they've had to adapt to a changing climate, a changing environment, and find places to call home, just as people do.”

Other images include:

• A star resting in an outstretched hand in honor of Octavia E. Butler, the science fiction writer who also spent time in the library. 
•  Quetzalcoatl, the feathered serpent Aztec deity and a frequent motif in East L.A.’s murals. 
• An owl, a symbol of knowledge associated with the Greek goddess Athena and the Roman goddess Minerva. 

González said the goal is for viewers to create their own narrative about what they see.

“ I just hope that people carry with them a sense of curiosity to further explore the things that I present, but also maybe something within them,” González said.
