This doesn't usually happen at Paris' destination of elegant grandeur, The Grand Palais. While the gorgeous glass-domed exhibition hall is no stranger to events such as fashion shows with labels like CHANEL, it is rather unprecedented to be house for the biggest vert ramp in Europe. Of course, who other thank Quiksilver would think to install a vert ramp of gargantuan proportions for skate enthusiasts and the name synonymous to skate--Tony Hawk-- to abuse for its 40th birthday? The 40th Anniversary Party not only featured Tony Hawk, but seven-time surf world champion, Kelly Slater was also present at the event. Some other brand ambassadors present for roll call include Reese Forbes, Alex Olson and Robby Naish. The celebration also called for a fashion show and live-art performance by Andre Saraiva. Check out the photos courtesy of WWD and a video from Quiksilver documenting the wild moments on the vert ramp.
