Allen's mask is painted blue and yellow, in the color scheme of both the Blues and the Blue Angels, and features the Blue Angel ribbon across the front bottom. On the right side are two Blue Angels shield and two Hornet jets, and the Blues logo is on the left side.
"I'm looking forward to wearing the mask in Monday's game," Allen said in a story posted to the Blues website. "It's a great tribute to the Blue Angel pilots who have the honor of flying and performing around the country."
According to the Blues website, the mask was a collaboration between Jason Livery, who designs Allen's masks, and employees at Boeing. Boeing has a significant presence in St. Louis and makes the F/A-18 Hornets the Blue Angels fly.
