The highly regarded alt-manga blog Same Hat! Same Hat! has some photos up of the amazing GARO exhibition at the Center for Book Arts in NYC.
I haven’t studied up much on GARO, but it seems to me (from a publisher’s perspective) that the presence of Shirato Sanpei’s “Kamui” was the financial tent pole that enabled all sorts of other experimental and daring work that was not necessarily sellable on its own. I’m planning on ordering one of the exhibition catalogs to learn more.
