It's not totally new... Phillies gave away the famous Larry Andersen masks back on "Halloween Night" in 1985, but Bleacher Creatures have expanded to making full face masks.
Phillies included are Roy Halladay, Jonathan Papelbon, and Cliff Lee. They also have Mike Vick, and Claude Giroux. They also sell a Sydney Crosby mask. Maybe there is something clever Flyers fans can do with that.
As Halloween approaches and with the existence of people that are lazy like me, this is the perfect item to make a quick costume. I will throw on a pair of jeans, my Jonathan Papelbon jersey, and a Papelbon face mask.
You can buy one here, on the Bleacher Creature website.
