Hard to find vtg Carman concert hat

Hard to find! Carman in Concert hat from around the year 2000. A black baseball cap with a stunning artistic red, black, and white logo on the front. The part that goes on your head is 7" diameter. There's dust on it. It can be gotten off, I just wasn't sure what to use for that. The back half of the dome has lost some stiffness, and there's a few small dangling threads. But overall very good condition!
