It's Pinky Webb on the June 2009 Cover of Rogue Magazine in their State of the Nation Issue. It also marks the anniversary of their controversial issue where Joey Mead was spray painted using the Philippine flag. [Joey Mead's Spray Painted Body on Rogue Magazine].
There are 2 more Pinky Webb photos inside that are said to be Behind the Scenes photos but doesn't really count as behind the scenes for me. Check them if you're a little curious. :D
