Similar to most sports, the celebration that follows a goal is often judged by fans for style and execution. Specifically in the NHL, the 'celly' has become somewhat of a competition within the game for who can have the best goal celebration. The celebration often varies based on the situation and player. Some of the variations include the hug, the raising of the arms over the head, a bird flocking, to name a few. Here is a piece of hockey memorabilia that shows Casey Mittelstadt of the Buffalo Sabres beginning his celebration by casually spreading his arms wide. Mittelstadt has autographed this 'Celebration' 20"x16" designed image in silver paint pen. His signature is deemed authentic by virtue of Upper Deck Authenticated's Five-Step Process.
