This is a MISFITS 20 YEARS OF TERROR 1977-1997 cap. I think I bought it when they came to Japan in 1997 (or maybe it was a gift...). The original color was black, and as you can see, it's really worn out. I wore it a lot. I couldn't find it when I searched online, so you could say it's rare... Please check the photos and make your own judgment.
