I mean, who in the world is going to buy merchandise/souvenirs that follow this theme?
imo the official t-shirts are usually pretty ugly no matter the theme that year. I think those things pretty much sell themselves. They could probably sell them with the tickets and a significant amount of people would buy them without even being given a peek. I usually buy a poster but I'd rather go with a nice individually designed screen-printed poster than the official lineup poster anyways.
