This could not be a sweeter, gentler piece. It's by the Japanese artist Yumeji Takehisa (1884 - 1934), and titled "Kurofuneya." (I've also seen it called "The Mistress of Kurofuneya.") Takehisa was not traditionally schooled, choosing to go his own way with his approach and style. As a result, though he didn't achieve high professional recognition, his work was immensely popular in everyday life. There's a museum about him in his hometown of Okayama; the English version of its site is here, and I do hope you find it charming. I did. Now let us all find a black cat and hug it well.
