The Bookworm Carl Spitzweg (1808-1885)

The picture has something of this: people, music, woman, man, musician, step, wear, portrait, singer, indoors, education, ladder, recreation, room, light, performance, boy, school.
Perhaps it’s a man standing on top of a ladder in front of a bookshelf with a book case full of books behind him and a light shining on the bookshelf.
