Sorry if I've already told you this, but other people may like it if they see it in comments.

Some 20 years or so ago, I bought abostick59 a "Goodbye Kitty" shirt. It features two of the main characters. One is pointing a little stylized gun at the other's right ear, and a stylized blob of blood is coming out of the second one's left ear. The type face is perfect.

I had to buy it like drugs. I had to give money to a blind drop and collect the t-shirt from a different third party, because Sanrio is so careful of its branding.

I love it. Sadly, it's stained and doesn't fit him any more, but knowing it's in the world is a delight.
