Signed copies of Amanda Palmer's book The Art of Asking and of her album (CD) Theatre is Evil. 

From the book jacket:

"Amanda Palmer is a world-renowned singer, songwriter, activist, director, and blogger who first came to prominence as one half of the internationally acclaimed punk cabaret duo The Dresden Dolls. She is a fellow at the Berman Center for Internet & Society at Harvard University and has shown her underwear on Australian television. Palmer's TED Talk, "The Art of Asking," which she presented at a 2013 TED conference, has been viewed at least 8 million times around the world."

Of the book, Bono writes, "Amanda has a direct line with her audience—a lifeline for them and for her, the codependency all truly great performers surrender to...She's capable of anything, incapable of telling anything but the truth."

On the album:

"Audacious Glam-Rock. Amanda Palmer's Theatre is Evil is full of spectacular moments of parody, irony, and sincerity. She's never been one to be subtle, and with her newly freed canvas, she (and the Grand Theft Orchestra) paints in some of the biggest strokes possible."
