at the piano 1908 Childe Frederick Hassam (1859-1935)

The picture has something of this: people, wear, veil, two, woman, group, ceremony, man, flower arrangement, furniture, mammal, bride, room, dress, wedding, side view, child.
Perhaps it’s a painting of a woman in a white dress sitting at a piano with a bouquet of flowers in front of her and a vase.
