Van Gogh's "Vase of Fifteen Sunflowers" is a famous still life painting created by Dutch painter Vincent van Gogh in 1888. This painting is part of his Sunflowers series created in Arles, France. Van Gogh's Sunflowers series consists of two still life paintings. The first series was created in Paris in 1887, depicting flowers lying on the ground, while the second series was created in Arles a year later, showcasing sunflower bouquets in vases. Van Gogh's Sunflowers series played an important role in his artistic career. He wrote in his letter to his younger brother that his sunflower paintings represent 'gratitude'.

Van Gogh's "Olive Tree" series was created by him between 1889 and 1890, mainly in Saint Remi, France. He voluntarily stayed in a mental hospital there for a year, during which he painted the hospital's garden, as well as nearby olive trees, cypress trees, and wheat fields when he obtained permission. The Olive Tree series holds a special significance for him. His painting 'The Olive Harvester' showcases the relationship between humans and nature. By depicting one of the cycles of life - harvesting or death - they also convey an example that individuals can connect with nature through communication with it. 'The Olive Tree' is currently housed at the Minneapolis Academy of Fine Arts.

This landscape of "Orville Scenery" located in the suburbs of Orville depicts a group of ancient rural cottages situated below a raised horizon; Further down, the wheat field extended all the way to the bottom of the canvas, and only a few swaying trees were broken. The narrow range of colors and tense, exciting brushstrokes, following repetition, are the characteristics of the artist's final works. Van Gogh painted a large number of landscape paintings in the weeks before his death, always working outdoors. By then, he had fallen into various conflicting emotions: the vast and fertile farmland gave him a sense of freedom, but at the same time, it also exacerbated his feelings of melancholy and loneliness, ultimately leading to his suicide.

The oil painting "Laksefskere p å Nes ø ya" was created by Norwegian painter Hjalmar Eilif Emanuel Peterssen in 1891 and is currently housed in the Minneapolis Museum of Art. This painting depicts salmon fishermen resting on Nesser Island near the Norwegian capital Oslo. Peterson successfully combines the ideas and techniques of French Impressionism with traditional Scandinavian painting in this painting.
