Van Gogh stayed within what he called the "guise of reality", and was critical of overly stylised works. He wrote afterwards that the abstraction of Starry Night had gone too far and that reality had "receded too far in the background". Hughes describes it as a moment of extreme visionary ecstasy: the stars are in a great whirl, reminiscent of Hokusai's Great Wave, the movement in the heaven above is reflected by the movement of the cypress on the earth below, and the painter's vision is "translated into a thick, emphatic plasma of paint".
The self-portraits reflect an unusually high degree of self-scrutiny. Often they were intended to mark important periods in his life, for example the mid-1887 Paris series were painted at the point where he became aware of Claude Monet, Paul Cezanne and Signac. In Self-Portrait with Grey Felt Hat, heavy strains of paint spread outwards across the canvas. It is one of his most renowned self-portraits of that period, "with its highly organized rhythmic brushstrokes, and the novel halo derived from the Neo-impressionist repertoire was what Van Gogh himself called a 'purposeful' canvas".
In preparation for Gauguin's visit, Van Gogh bought two beds on advice from the station's postal supervisor Joseph Roulin, whose portrait he painted. On 17 September he spent his first night in the still sparsely furnished Yellow House. When Gauguin consented to work and live in Arles with him, Van Gogh started to work on the Décoration for the Yellow House, probably the most ambitious effort he ever undertook. He completed two chair paintings: Van Gogh's Chair and Gauguin's Chair.
The sunflowers were painted to decorate the walls in anticipation of Gauguin's visit, and Van Gogh placed individual works around the Yellow House's guest room in Arles. Gauguin was deeply impressed and later acquired two of the Paris versions. After Gauguin's departure, Van Gogh imagined the two major versions of the sunflowers as wings of the Berceuse Triptych, and included them in his Les XX in Brussels exhibit. Today the major pieces of the series are among his best known, celebrated for the sickly connotations of the colour yellow and its tie-in with the Yellow House, the expressionism of the brush strokes, and their contrast against often dark backgrounds.
Van Dyke began his film career by playing the role of Albert J. Peterson in the film version of Bye Bye Birdie (1963). Despite his unhappiness with the adaptation—its focus differed from the stage version in that the story now centered on a previously supporting character—the film was a success. That same year, Van Dyke was cast in two roles: as the chimney sweep Bert, and as bank chairman Mr. Dawes Senior, in Walt Disney's Mary Poppins (1964). For his scenes as the chairman, he was heavily costumed to look much older and was credited in that role as "Navckid Keyd" (at the end of the credits, the letters unscramble into "Dick Van Dyke"). Van Dyke's attempt at a cockney accent has been lambasted as one of the worst accents in film history, cited by actors since as an example of how not to sound. In a 2003 poll by Empire magazine of the worst-ever accents in film, he came in second (to Sean Connery in The Untouchables, despite Connery winning an Academy Award for that performance). According to Van Dyke, his accent coach was Irish, who "didn't do an accent any better than I did", and that no one alerted him to how bad it was during the production. Still, Mary Poppins was successful on release and its appeal has endured. "Chim Chim Cher-ee", one of the songs that Van Dyke performed in Mary Poppins, won the Academy Award for Best Original Song for the Sherman Brothers, the film's songwriting duo.
On January 27, 2013, at the age of 87, Van Dyke received the 2013 Screen Actors Guild Life Achievement Award. During his acceptance speech, Van Dyke reminisced about his work over the years as an entertainer and stated that his career has "been full of surprises and a lot of fun." He also praised actors working in the industry today, calling them "the greatest generation of actors" and telling them, "You've all lifted the art to another place now." He continued with a rhetorical question for his Hollywood colleagues: "Aren't we lucky to have found a line of work that doesn't require growing up? I love that." Van Dyke is the 49th recipient of the SAG Life Achievement Award, following 2012 honoree Mary Tyler Moore.
