Just passing along info:
You can order from here, allegedly. I cannot vouch for that, nor that there is, in fact, international shipping, but it’s worth looking into if you’ve not only always wanted a Hanako-san T-shirt, but wanted a Hanako-san T-shirt that depicts here as one of the Garbage Pail Kid.
Note that the red version was/is sold only at events, so it’s white or nothing. I say get it, then wear it to a GWAR show and make friends.
