Flameng, Francois. Portrait of Princess with her two sons in the Arkhangelsk Hermitage ~ part 12

The picture has something of this: dress, wedding, woman, people, veil, bride, girl, wear, outdoors, fashion, traditional, flower, love, beautiful, fall, summer, person, marriage.
Perhaps it’s a painting of a woman in a white dress holding a cane and walking a dog in front of a park bench with a young boy in the background.
