I have a chrome AOII on the back of my car that looks really nice. I actually got our Emporium to start selling it. I paid $30 for mine on eBay and now they sell it for $10.
Oh well. I wear my badges all the time, and occasionally wear a shirt with AOII embroidered at the top or a screen print shirt from convention. I never wear really big lettered shirts except for last Saturday I wore one to a spring training game for an alum event so we could spot each other in the crowd. I got some really weird looks. It did it's job though!
