Equestrian Portrait of a Boy 

"Equestrian Portrait of a Boy" is a painting by George Washington Lambert, an Australian-born American artist known for his portraits and landscapes. The painting depicts a young boy, likely from a wealthy family, dressed in a red coat and breeches, sitting on a horse with an older girl standing beside him. The painting's composition, with its soft lighting and the figures' relaxed postures, suggests an intimate snapshot of a moment in the lives of the two children.
