Influence is an upcoming coffee table book by Mary Kate & Ashley Olsen due for release in the US, in late October. Influence will have two covers available, one featuring Mary Kate with Ashley on the back, and the reverse for the 2ND cover. The girl's agent says, "the girls take a journey through their young lives, reflecting on what has shaped them, have written short essays on each other and interviewed 20 people". Interviews include Karl Lagerfeld, Diane Von Furstenburg, John Galliano, Christian Louboutin and Lauren Hutton. The interviewees have provided some of their own photos and drawings, as well as never before seen photos of the girl's own private collection.
