I have a jacket that I had made in Korea many years ago, back when I was an active observer. It has the AAVSO logo on the back and my name -- Steve -- on the front.
I am no longer active, and have outgrown the jacket (it's a Large). It did not see a lot of use, so it's in pretty good condition.
If anyone wants it, send me your surface mail address (to sshervais@gmail.com) and I'll ship it to you.
