Is this legal? 18-1?

not even kidding we have a t-shirt machine in our school n right before the superbowl a bunch of shirts were made before the superbowl with moss' pic that said "got moss?" im wondering if 18-1 has been trademarked or anything yet because i wanna know if i can make a bunch of 18-1 t-shirts n sell them if it has been ill jus have to go with my other idea of puting belichicks pick on with "got loss?" haha
