Looking for the name of a painting with a woman in orange gown standing next to a seated man.?

My grandmothers copy was destroyed and I want to replace it for her. The people are dressed in an older style clothing. The man is either seated at a desk or a piano and she is standing with her hand on his shoulder. She has on a wide skirt orange/peach dress. Any help locating a print of this painting would be helpfull. Thank you.
