Graduation photo

My nephew Nick is graduating from high school this month. Along with an invitation to the graduation ceremony and party, he included this excellent photo.

That's a paintball gun, and a studio prison door—right? Looks scary. On my last visit to a photography studio I didn't see the "Jailhouse" set, but maybe I didn't know to ask.

I think he plays on a team that's named the Expendable Heroes? Or something like that? Alison? Nick?
