Latelier au mimosa, 1939, 125x125 cm, Musee Nationa Pierre Bonnard

The picture has something of this: picture frame, antique, dirty, vintage, retro, rusty, artistic, design, paper, texture, brush, stain, abstract, wall.
Perhaps it’s a painting of a yellow room with a potted plant on the window sill and a staircase leading up to the second floor of the room.
