Chicago Cubs stars Kris Bryant and Anthony Rizzo will be signing autographs on Saturday evening, but if fans want to participate, they’re going to have to shell out some serious coin.

The autograph signing, which is being hosted by Fanatics Authentics, will feature both Cubs stars at the Radisson Blu hotel in downtown Chicago. The signing will get underway at 6:30 p.m., but fans will have to buy tickets to participate.

Just how much do those tickets cost? A cool $699 apiece.

The event is being billed as the first public signing that the two players have participated in since they helped the Cubs capture the World Series championship last fall.

The nearly $700 price tag will entitle the ticketholder to one autograph apiece from both Bryant, the 2016 National League MVP, and Rizzo, the man who caught the final out in Game 7 of the World Series.
