Great stuff!

That series of 100 woodblock images, each including the moon in some part, is called the "
Tsuki Hyakushi." The artist, himself, was Yoshitoshi Tsukioka. He's easily my favorite
ukiyo-e artist. His style was a major influence on Frank Miller (of comics' Daredevil, The Dark Knight, and Sin City fame).
I really hope to see some of these images in an OAUA mod, someday!
