Per Roc Nation CEO Desiree Perez, the response to the exhibit has thus far ben “truly overwhelming” for all involved.

“We staged the exhibit at the Brooklyn Public Library, to serve as a reminder that genius lives in us all and there should be no barrier to knowledge and opportunity,” Perez said in a press release. “Collaborating with Christie’s for this auction is an honor and I hope that the spirit of The Book Of HOV serves as an inspiration for others to consistently support vital community institutions.”

Jay’s signature is seen on the inside of the Pinel et Pinel case, which also comes with a metal bookmark and a commemorative card in the single-lot auction. As for those one-of-a-kind metal library cards, fans will note that they are indeed replicas of the cards made for exhibit attendees, with each one boasting the cover art from a different Jay album.

Bids are now being accepted, with the auction slated to come to a close on Dec. 5. Get a closer look at the lot below.

In September, a certain off-white Lexus was added to the wildly popular exhibit, which launched this summer with a star-stacked grand opening event. A number of noteworthy archival pieces are featured in the exhibit, including the guitar Jay used to troll Noel Gallagher with some “Wonderwall.”
