The Charles Franks House is a historic house located at 34431 U.S. Route 52 east of Lanark, Illinois.
 The house was built circa 1950 by Charles Franks, a prominent settler and local landowner.
 The site of the house had previously been home to Isaac Chambers' tavern and stagecoach stop on the Galena Road; the tavern also became a shelter for troops and a target for warring Native Americans in the Black Hawk War.
 The house's design is a vernacular implementation of the Federal style, which was prevalent in the United States earlier in the 19th century but had faded from popularity by 1850.
 While the house features the style's typical hipped roof and jack arch lintels above the windows, it is smaller than most Federal houses and is missing characteristic decorations such as a fanlight above the front door.
The Charles Sumner School, established in 1872, was one of the earliest schools for African Americans in Washington, D.C.

 It currently houses a small museum, a research room, art exhibits, and the archives of the District of Columbia Public Schools.

The Cavalier King Charles Spaniel is a small spaniel classed as a toy dog by The Kennel Club and the American Kennel Club.
 It originated in the United Kingdom and is one of the more popular breeds in many countries.
 Since 2000, it has grown in popularity in the United States and ranks as the 18th most popular pure-breed in the United States (2013 Registration Statistics).
 It has a silky, smooth coat and commonly a smooth undocked tail.
 The breed standard recognizes four colours: Blenheim (chestnut and white), Tricolor (black/white/tan), Black and Tan, and Ruby.
 The breed is generally friendly, affectionate and good with both children and other animals; however, they require a lot of human interaction.
 Since they are a family dog, it is recommended to not leave them alone for long periods at a time.
 The expected average lifespan of a Cavalier King Charles Spaniel is under ten years.
Sacco e Vanzetti is an Italian docudrama written and directed by Giuliano Montaldo that premiered in Italy on 16 March 1971.
 The story is based on the events surrounding the trial and judicial execution of Nicola Sacco and Bartolomeo Vanzetti, two anarchists of Italian origin, who were sentenced to death by a United States court in the 1920s.
 The film's musical score was composed and conducted by Ennio Morricone with the three-part ballad sung by Joan Baez.
 The film is mainly shot in colour although it both starts and finishes in black and white, and also includes period black and white newsreels.
What Happened to Mary (frequently erroneously referred to in various texts as "What Happened to Mary?"
 — but the title was a statement, not a question) is the first motion picture serial made in the United States.
 Made by Edison Studios, the action serial consisted of twelve one-reel episodes released monthly beginning July 26, 1912 to coincide with the serial story of the same name published in McClure's "The Ladies' World" magazine.
 "What Happened to Mary" was performed as a stage play and published as a single-volume print novel, so is an early example of a multiple-media marketing campaign.
 The scripts were written by Horace G. Plympton and directed by Charles Brabin.
 The star of the serial was Mary Fuller.
Lake Charles State Park is a 140 acre Arkansas state park in Lawrence County, Arkansas in the United States.

 Construction on the lake began in 1964, and the park was dedicated in 1967.
