This is a Howl T-shirt from the 1990s from Howl's Moving Castle.
I purchased it at a pop-up store in a vintage clothing store specializing in anime T-shirts, so I have complete confidence in the product.
Ghibli T-shirts are becoming increasingly expensive, and this item was even sold by Avalon, a company famous for its anime T-shirts.
The price is incredibly low, so collectors and Ghibli fans should definitely get it.
