Post-expressionism is a term coined by the German art critic Franz Roh to describe a variety of movements in the post-war art world which were influenced by expressionism but defined themselves through rejecting its aesthetic.
 Roh first used the term in an essay in 1925, "Magic Realism: Post-Expressionism", to contrast to Gustav Friedrich Hartlaub's "New Objectivity", which more narrowly characterized these developments within German art.
 Though Roh saw "post-expressionism" and "magic realism" as synonymous, later critics characterized distinctions between magic realism and other artists initially identified by Hartlaub and have also pointed out other artists in Europe who had different stylistic tendencies but were working within the same trend.
Andrew Newell Wyeth ( ; July 12, 1917 – January 16, 2009) was a visual artist, primarily a realist painter, working predominantly in a regionalist style.
 He was one of the best-known U.S. artists of the middle 20th century.
Marvin Cone (October 21, 1891– May 18, 1965) was an American painter in the regionalist style.
Russ Warren (born 1951) is a contemporary figurative painter who has exhibited extensively throughout the U.S. and abroad, notably in the 1981 Whitney Biennial and the 1984 Venice Biennale.
 A painter in the Neo-Expressionist style, he has drawn inspiration from Spanish masters such as Velázquez, Goya and Picasso, as well as from Mexican folk art and the American southwest.
 Committed to his own Regionalist style during his formative years in Texas and New Mexico, he was picked up by Phyllis Kind in 1981.
 During those years he transitioned to a style characterized by "magical realism", and his work came to rely on symbol allegory, and unusual shifts in scale.
 Throughout his career, his paintings and prints have featured flat figures, jagged shadows, and semi-autobiographical content.
 His oil paintings layer paint, often incorporate collage, and usually contain either figures or horses juxtaposed in strange tableaux.
Magical realism, magic realism, or marvelous realism is a genre of narrative fiction and, more broadly, art (literature, painting, film, theatre, etc.) that, while encompassing a range of subtly different concepts, expresses a primarily realistic view of the real world while also adding or revealing magical elements.
 It is sometimes called fabulism, in reference to the conventions of fables, myths, and allegory.
 "Magical realism", perhaps the most common term, often refers to fiction and literature in particular, with magic or the supernatural presented in an otherwise real-world or mundane setting.
James H. Cromartie is an internationally renowned American artist credited with the birth of Hard-Edge Realism, a style by turns both redolent of and a departure from the Magic Realism pioneered by Andrew Wyeth.
 The list of celebrities and wealthy patrons reported to be among his collectors is extensive and examples of Cromartie’s work may be found in 125 countries across the globe.
 Domestically, Cromartie has been called, “one of America’s leading historical artists,” for his commissioned portraits of the White House, Smithsonian Institution, U.S Capitol and Supreme Court, among others.
 In 2005, James H. Cromartie’s historical portrait of the White House was featured in the widely distributed art history textbook, ArtTalk, a distinction granted to a mere 25 living artists globally.
 Cromartie has resided year-round on Nantucket, Massachusetts for over 35 years, proudly quipping, “there are Nantucket artists, but then again there are…artists who have chosen to live on Nantucket.
 There’s a b-i-g difference.”
George Clair Tooker, Jr. (August 5, 1920 – March 27, 2011) was an American figurative painter.
 His works are associated with Magic realism, Social realism, Photorealism and Surrealism.
 His subjects are depicted naturally as in a photograph, but the images use flat tones, an ambiguous perspective, and alarming juxtapositions to suggest an imagined or dreamed reality.
 He did not agree with the association of his work with Magic realism or Surrealism, as he said, "I am after painting reality impressed on the mind so hard that it returns as a dream, but I am not after painting dreams as such, or fantasy."
 In 1968, he was elected to the National Academy of Design and was a member of the American Academy of Arts and Letters.
 Tooker was one of nine recipients of the National Medal of Arts in 2007.
William Moise (1922–1980) was a visual artist, primarily an abstract impressionist painter, working in a regionalist style.
The Sydney School, also the Nuts and Berries style, refers to an architectural style by a group of architects in Australia who reacted against international Modernism with their own regionalist style during the 1960s.
 In contrast to the purism of the international style, they were drawn to rustic materials, clinker bricks, low gutter lines, and raked roof lines rather than flat roof lines.
Carroll Nathaniel Jones III (July 2, 1944 - June 22, 2017) was an artist in the style of American realism.
 Carroll grew up in New Providence, New Jersey where his father, an illustrator for Life (magazine), was his first art teacher.
 He taught Carroll techniques of the Old Masters, who emphasized light, perspective, and composition.
 Carroll went to school in New York City (NYC) and enrolled in the Phoenix School of Design at age 17.
 He later attended Hartford Art School and became a commissioned portraitist for 10 years.
 His work, "Church Window" was recognized in the New York Times, and he moved away from portraits to recreate scenes that sparked memories of his childhood.
 He was most influenced by Andrew Wyeth and Edward Hopper.
 The Coe-Kerr Gallery of NYC and Whistler's Daughter Gallery of New Jersey represented him, as well as contemporaries Wyeth and Hopper.
 Malcolm Forbes, Frederick R. Koch, Stephen Sondheim, William Schuman, and Jean Shepherd held private collections of his work.
 He exhibited at Newark Museum and Trenton Art Museum in New Jersey, and in universities, galleries and museums in seven states by his mid-thirties.
 His work is part of the permanent collections of Seton Hall University and Newark Museum.
 Art critic Marion Filler considered his work Magic realism, a quiet movement made popular in America beginning in the 1920s by Hopper, and related to Surrealism.
