The World's Largest Pop-Up Book is 30 Feet Wide

This is Luceros y Penumbras, a one-of-a-kind pop-up book currently on display at the main branch of the Los Angeles Public Library. The Library Foundation for Los Angeles informs us that it measures 30 feet by 21 feet and the pop-ups are 11 feet high.

Don't expect to check it out from the library. The book weighs 1,800 pounds! LAist reports that artist Daniel González and paper engineer Matthew Reinhart worked together to design and build this book made out of linoleum. It has four pages and two scenes that pop up as they are opened. You can visit and read it at the library until November.
