As explained here at the Rijksmuseum. Never thought I would be discovering our national paintings on Danbooru featuring Touhous. Checking the artist's pixiv page, he/she has a lot more.

I love these art parodies. Especially when they're as well done as here.

This --- and the rest --- really are extraordinarily good. And this one is very apt.

This has something special.

I want to print this on a canvas and hang it on my room.
