I found a Mark Brunell jersey at the Salvation Army today, and so I grabbed it to send it to him to get it to sign. Is there any prep-work I need to do to it before I send it?

I also found some old mini helmets (three team USA, a Yellow P pirates helmet, and possibly a few other things not sure) is there any prep I need to do to them before sending them. I'm thinking about sending one of the Team USA to Mcquire, because it was his year on the olympic team, but IDK if he signs well.
