Nevertheless, the twelve customers selected the colors and styles they desired, and were asked to return later in the afternoon to pick up their purchases. Paul Van Doren and Lee then rushed to the factory to manufacture the selected shoes. When the customers returned that afternoon to pick up their shoes, Paul Van Doren and Gordon C. Lee realized that they had forgotten to maintain a cash reserve to provide change to customers. The customers were therefore given the shoes and asked to return the following day with their payments. All twelve of the customers returned the following day to pay for their items.
Many of the late paintings are sombre but essentially optimistic and, right up to the time of Van Gogh's death, reflect his desire to return to lucid mental health. Yet some of his final works reflect his deepening concerns. Writing in July 1890, from Auvers, Van Gogh said that he had become absorbed "in the immense plain against the hills, boundless as the sea, delicate yellow".
There was interest from a dealer in Paris early in 1885. Theo asked Vincent if he had paintings ready to exhibit. In May, Van Gogh responded with his first major work, The Potato Eaters, and a series of "peasant character studies" which were the culmination of several years of work. When he complained that Theo was not making enough effort to sell his paintings in Paris, his brother responded that they were too dark, and not in keeping with the bright style of Impressionism. In August his work was publicly exhibited for the first time, in the shop windows of the dealer Leurs in The Hague. One of his young peasant sitters became pregnant in September 1885; Van Gogh was accused of forcing himself upon her, and the village priest forbade parishioners to model for him.
Van Gogh made several painting excursions during visits to the landscape around Arles. He made paintings of harvests, wheat fields and other rural landmarks of the area, including The Old Mill (1888); a good example of a picturesque structure bordering the wheat fields beyond. At various points, Van Gogh painted the view from his window – at The Hague, Antwerp, and Paris. These works culminated in The Wheat Field series, which depicted the view from his cells in the asylum at Saint-Rémy.
Van Gogh created more than 43 self-portraits between 1885 and 1889.[note 13] They were usually completed in series, such as those painted in Paris in mid-1887, and continued until shortly before his death. Generally the portraits were studies, created during introspective periods when he was reluctant to mix with others, or when he lacked models, and so painted himself.
