Edit: Elliott was traded to the Colorado Avalanche in Februrary 2011. I will keep his Sens mask photos down at the bottom of the entry, since he was there over half the season.
This is all I have of the Avs mask so far.
From The Goalie Guild: "Casey Jones is sprawling over the top of the mask, with the main Senator logo on the right side of the mask and the “O” secondary flag logo on the right side of the mask."
Casey Jones is the hockey mask-wearing, stick-swinging vigilante who fought crime alongside the Teenage Mutant Ninja Turtles in the cartoons and the first movie.
