The Divje Babe flute, also sometimes called the tidldibab or Neanderthal flute, is the femur of a cave bear, which is pierced by spaced holes similar to those found on a flute. The object was unearthed at Divje Babe I, a cave site near Cerkno in northwestern Slovenia in 1995, during systematic archaeological excavations in the area. It is possible that it was made by Neanderthals as a form of musical instrument, although this theory is debated by scientists: some argue that the holes in the bone were artificially made by Neanderthals, while others say they were made by carnivores. If confirmed as a musical instrument, it would be the oldest-known Paleolithic flute and musical instrument. The object is now in the collection of the National Museum of Slovenia in Ljubljana.

Petasites hybridus, the butterbur, is a species of herbaceous perennial flowering plant in the family Asteraceae native to Europe and northern Asia. Although used over centuries in traditional medicine to treat various disorders and sometimes sold as a dietary supplement, it has no approved medical uses. Concerns about the potential toxic effects of pyrrolizidine alkaloids limit its use in human and animal studies. This P. hybridus inflorescence was photographed in a forest near Keila in northwestern Estonia.

His Majesty is an 1897 comic opera with dialogue by F. C. Burnand, lyrics by R. C. Lehmann, additional lyrics by Adrian Ross, and music by Alexander Mackenzie. The work premiered at the Savoy Theatre in London on 20 February 1897, running for only 61 performances until 24 April, despite a strong cast including George Grossmith, Ilka Pálmay, Scott Russell, Fred Billington, Florence Perry and Walter Passmore. The D'Oyly Carte Opera Company then toured the opera throughout 1897 alongside more familiar Gilbert and Sullivan works. This poster for His Majesty was designed by Dudley Hardy to advertise the original D'Oyly Carte production, or the tour immediately following.

La Fuensanta is a portrait painting by Spanish artist Julio Romero de Torres depicting Maria Teresa López González, one of his models. The painting was made in the autumn of 1929, when Torres completed another two artworks, La Chiquita Piconera and Bodegas Cruz Conde. González was one of Torres's favourite models, having first sat for him at the age of fourteen. According to Sotheby's, the work has been "proclaimed as a quintessential rendition of Andalucian beauty", and it was depicted for 25 years on the 100 peseta banknote. The work was exhibited at the Ibero-American Exposition in Seville in 1930, and is now in a private collection.

The Palácio Rio Negro is a palace in Petrópolis in the state of Rio de Janeiro, Brazil. One of the official residences of the president of Brazil, it is used mainly as a country retreat. The palace was designed by the Italian architect Antonio Jannuzzi in 1889 and built in the same year as a summer residence for Manuel Gomes de Carvalho, Baron of Rio Negro. He moved to Paris in 1894, leaving the building empty, and in February 1896 the palace and adjacent buildings were sold to the state of Rio de Janeiro to serve as the official residence of the state governor. It was then acquired by the federal government of Brazil in 1903, becoming the official presidential summer residence. This photograph depicts the façade of the Palácio Rio Negro in 2015.

Pinnularia is a genus of freshwater algae in the class Bacillariophyceae, the diatoms. An elongated elliptical unicellular organism, it is usually found in ponds and moist soil. The cell walls are composed chiefly of pectic substances on a rigid silica framework, and are composed of two halves known as thecae (or, less formally, valves). This Pinnularia major specimen, about 0.3 millimetres (0.012 in) in length, was photographed through a light microscope.
