Famous paintings celebrating mother's love

My Mother, Bolton Abbey, Yorkshire, by David Hockney, 1982 [Photo/Artron.net]

In this artwork, David Hockney portrays a woman wearing a cheap raincoat who seems quite lonely, using the photo collage. At the bottom, a pair of expensive leather shoes are shown on purpose as a contrast. The artist wants to show his and his mother's difficult situation and their desperate life.
