JAY-Z's Upcoming 'Book Of HOV' Auction Fuels Fan Theories About New Album

JAY Z's latest announcement is fueling more speculation about his next studio LP.

On Wednesday night, November 29, Roc Nation and Christie's Auctions revealed a one-of-a-kind memorabilia that commemorates the successful "Book Of HOV" exhibit at the Brooklyn Public Library. The black leather briefcase made by Pinel et Pinel and signed by Hov himself contains 14 limited metal library cards inspired by his classic discography. There are 13 cards in total that represent each album as well as an exclusive bookmark with the exhibit's name on it. However, some fans believe the "bookmark" is a literal placeholder for JAY-Z's 14th album.

“Every day for the past four months, thousands of new patrons have visited Central Library to see The Book of HOV and be inspired by Jay-Z’s extraordinary journey from Brooklyn to the world stage," Brooklyn Public Library President and CEO Linda Johnson told PEOPLE about the exhibit's impact. “We are grateful for the continued support and generosity of Roc Nation and Jay-Z fans across the world."

The last album JAY-Z released was 4:44 in 2017. Since then, he's hopped on select collaborations including DJ Khaled's "GOD DID" which was nominated for several Grammy awards. He's reportedly set to release new music on the soundtrack for the upcoming film The Book Of Clarence that arrives in January 2024. Hov actually made an Instagram account to promote the film, which is another indication that more updates are on the way.

The single-lot auction is officially open on Christies.com and will last until Dec. 5, which coincides with the final days of the exhibit.
