The first four are by the American painter and printmaker Mary Cassatt.
(Nurse Reading to a Little Girl)
(Young Woman with Auburn Hair in a Pink Blouse)
This next one is by the English artist Luke Fildes. I'm not sure what its title is, but it's very beautiful nonetheless.
And this final, equally beautiful painting, is by the artist William Llewellyn, and is titled Girl with Pigtails.
