I started giving pins at my old school that said "School Mascot Band Senior". The students were able to wear them on their uniforms, except at UIL, on the collar and were able to wear it at concerts with their concert black.

At my current school we do a T-shirt that says "School Mascot Band Alumni" and give it to them at the banquet, along with a paperweight that is engraved with Band Senior and their year.
