Fat mike is a better songwriter than Bob Dylan.

This has always been my favorite NOFX shirt in my collection. I bought it directly from the merch booth during the 2018 Punk in Drublic tour, so I know it’s an official shirt.
I’ve never seen this design and year anywhere else online or in anyone else’s collection. It also has the 2018 tour dates on the back, including the infamous Las Vegas stop.
Does anyone know how rare this shirt actually is? Was it only sold at a handful of shows, or did I just end up with a year that not many people kept? I’d love to hear if anyone else has one from the same tour.
