Arthur Devis, English, 1712-1787 – Portrait of the Right Honorable Thomas Penn Philadelphia Museum of Art

The picture has something of this: people, portrait, doorway, wear, woman, door, museum, model, furniture, room, indoors, home, man, outerwear, girl, window.
Perhaps it’s a painting of a man in a brown outfit standing in an open doorway with a white glove in his hand and a black cat in his other hand.
