The decade of the 1980s in Western Cinema saw the return of studio-driven pictures, coming from the filmmaker-driven New Hollywood era of the 1970s.
 The period was when "high concept" films gained popularity, where movies were to be easily marketable and understandable, and, therefore, they had short cinematic plots that could be summarized in one or two sentences.
 The modern Hollywood blockbuster is the most popular film format from the 1980s.
 Producer Don Simpson is usually credited with the creation of the high-concept picture of the modern Hollywood blockbuster.
Robert Bernard Altman ( ; February 20, 1925 – November 20, 2006) was an American film director, screenwriter, and film producer.
 A five-time nominee of the Academy Award for Best Director and an enduring figure from the New Hollywood era, Altman was considered a "maverick" in making films with a highly naturalistic but stylized and satirical aesthetic, unlike most Hollywood films.
 He is consistently ranked as one of the greatest and most influential filmmakers in American cinema.
The Women Painters of Washington is a non-profit organization based in the U.S. state of Washington.
 The group was formed on October 6, 1930 by six female artists who met while attending a portrait class sponsored by the Art Institute of Seattle, which was a predecessor to the Seattle Art Museum.
 The women joined together in order to overcome the limitations they faced as female artists and to stimulate their artistic growth through fellowship.
 Founding members were Elizabeth Warhanik, Dorothy Dolph Jensen, Lily Norling Hardwick, Myra Albert Wiggins, Anna B. Stone and Helen Bebb.
 Originally called the Women Artists of Washington, their first exhibition was held at the Women's Century Club on Seattle's Capitol Hill.
 Subsequent annual exhibitions were usually held at the Frederick & Nelson department store in downtown Seattle.
 In 1936 the name was changed to Women Painters of Washington.
New Hollywood, sometimes referred to as the "American New Wave", usually refers to a movement in American film history from the mid-to-late 1960s ("Bonnie and Clyde", "The Graduate" and "Easy Rider") to the early 1980s ("Heaven's Gate", "One from the Heart") when a new generation of young filmmakers came to prominence in United States, influencing the types of films produced, their production and marketing, and the way major studios approached film-making.
 In New Hollywood films, the film director, rather than the studio, took on a key authorial role.
 The definition of New Hollywood varies, depending on the author, with some of them defining it as a movement and others as a period.
 The span of the period is also a subject of debate, as well as its integrity, as some authors, such as Thomas Schatz, argue that the New Hollywood consist of several different movements.
 The films made in this movement are stylistically characterized in that their narrative often strongly deviated from classical norms.

The Joseph F. and Anna B. Schrot Farm is a 17 acre subsistence farm located at 880 Carbon Mine Road in Lawrence Township, Clearfield County, Pennsylvania.
 The farm was established in 1889 by Joseph F. and Anna B. Schrot, a stonemason and his wife who immigrated to Clearfield County from Austria in 1883.
 Stone quarries at nearby Curwensville had created a local demand for masons, and Joseph Schrot was one of many Europeans who came to Clearfield County to take construction work.
 The Schrots' farm provided food for the couple and their family of fourteen children; the couple sold their excess food for additional income.
