World's Largest Pop-Up Book at Los Angeles Public Library Sets Guinness Record
The Los Angeles Public Library has officially set a new Guinness World Record with its massive pop-up book, Luceros y Penumbras, making it the largest ever created. This impressive book, which weighs 1,800 pounds and spans 31 by 20 feet when opened, features pop-ups that rise over 11 feet high. It was introduced on July 11, 2026, during a celebration for the library's 100th anniversary at the Richard J. Riordan Central Library's Rotunda. The book draws inspiration from artist Vincent Valdez González's family and childhood, with a three-dimensional design by paper engineer Matthew Reinhart. To ensure safety, staff had to help turn its pages. The launch was part of a free Centennial Festival featuring music, workshops, author talks, and six exhibitions.
