For the 40th anniversary issue of W Magazine, the mag is celebrating by featuring four actresses on four covers in looks from four different eras. Rooney Mara, Mia Wasikowska, Scarlett Johansson, and Keira Knightley each don a different decade on the cover of this birthday edition. 

In the forty years W Magazine has been in existence, it has had many different celebrities and stars on its front page. This month for its 40th Anniversary Edition, the mag has not one, but four cover girls. Rooney Mara, Mia Wasikowska, Scarlett Johansson, and Keira Knightley each are as if they are from the '70s, '80s, '90s, and Aughts respectively on this month's issue of W.

The mag will be available for purchase starting October 23rd, but until you can own the physical copy flip through the four covers and try to determine which starlet looks like she truly belongs from the decade she is dressed in.
