Johann Peter Hasenclever (1810 – 1853) – The Reading Room Alte und Neue Nationalgalerie (Berlin)

The picture has something of this: people, group, furniture, woman, administration, man, room, leader, many, several, recreation, education, wear, sit, music, seat, war, military.
Perhaps it’s a painting of a group of men sitting around a table in a room with papers on the table.
