caption: This is a black and white picture. In this picture, we see the posters or the banners of the charts are pasted on a white wall. We see the text written on the posters. In the middle, we see a table on which the papers or the charts are placed and we see the shelves on which the posters are placed. We see a black T-shirt is hanged to a hanger. Beside that, we see a switchboard and a cable. We see the boards and a lamp are placed on a wall. At the bottom, we see the floor, a black color object which looks like a sofa and a table on which an object is placed. On the right side, we see a table on which a monitor and the objects are placed. We see the photo frames and the objects are placed on a wall. In the left bottom, it looks like a rod.
