Ever since Taylor Swift kicked off her Eras Tour, fans have had questions about the infamous cleaning cart — and now we’re getting answers. For the uninitiated, Swift, 34, is transported to the stage via an unassuming black “cleaning cart” before popping out to perform.

Swifties braved Black Friday to get their hands on a copy of Taylor Swift's Eras Tour book. Here are revelations from the groundbreaking world tour.

The new keepsake, titled "Taylor Swift | The Eras Tour Book," is available only at Target. It hits the retailer's stores on Friday, while it will become available for sale on Target's website on Saturday. Swift self-published the book under Taylor Swift Publications.
