it should be tagged Kurehito Misaki cuz that's the artist that drew the pic.
comment #38984 Get yourself a copy of "Stem of Radiant", The Alstromeria/Crade Artbook/Muisc-thingy from last year. It's hardcover and an extremely sploogetastic thing if you like pwetty touhou pictures.
No idea about its availabilty at this timepoint, though.
