That's the reason it caught my eye; my college fraternity (ATO) incorporated the Maltese cross in a lot of our imagery. I don't think it's related, just thought it was interesting. It was near some pins from the Shriners and Masons, so it might have something to do with an organization like that.It’s a star on a blue Maltese cross. Is this like the lady in the hat or old lady thing?
It means you where in the marching band all 4 years of high school.
In my HS if you were in marching band you got a varsity letter because it was a competitive activity (to note, one of the best MBs in North Carolina).
A lot of nasty looks from the athletes every spring when all the lettermen/women got together for a group pic for the yearbook lol (I got my letter in MB, also wrestling).
Off topic a bit but Kids are more accepting now. I think its fine to letter in band because those kids put a lot of effort into their craft just as an athlete does. When I was in school we used to say Soccer was for kids who couldn't play real sports. Now, Soccer is one of the biggest sports. FWIW, I lettered in Baseball.
