Update: January 2015 - Andersen added one more mask this season...a tribute to Teemu Selanne that he wore during Selanne's jersey retirement ceremony on January 11th.
Andersen seems to already have 2 (now 3) different masks this season, although I'm not sure that he's worn the 2nd one yet (I couldn't find in-game photos yet anyway.)
David Gunnarsson is the artist for both masks.
He began the season with a LEGO Movie themed mask.
But then a few days ago it was announced he would have a new "Reservoir Ducks" themed mask (a twist on the movie, Reservoir Dogs.)
...if you have seen the Reservoir movie you will see Mr. Blonde is not a very nice guy...An on the side of the mask you will find Mr. Blonde again, with his team, as ducks of course...And he is holding his razor...
And on the other side the Ducks logo, and as a true Reservoir Duck of course he wears sunglasses.
