La Lecture (or Reading) is a painting by Spanish artist Pablo Picasso completed in January 1932.
 The oil painting depicts Picasso's mistress and muse, Marie-Thérèse Walter, asleep with a book upon her lap.
 The painting led to the breakup of Picasso's marriage to Olga Khokhlova after she saw it at a retrospective exhibition and realised that the facial features were not her own.
 The painting went to auction in 1989 and in 1996, where it failed to sell.
 In January 2011, it was announced that "La Lecture" would be going to auction on 8 February.
 The painting, which had not been seen in Europe since the exhibition, was then displayed at Sotheby's in Paris.

Astro Boy (アストロボーイ・鉄腕アトム , Asutoro Bōi: Tetsuwan Atomu , lit.
 "Astro Boy: Mighty Atom") is a remake of the 1960s anime series of the same name created by Osamu Tezuka, which was produced by his company, Tezuka Productions, Sony Pictures Entertainment Japan, Dentsu, and Fuji Television network.
 It was also shown on Animax, who have broadcast the series across its respective networks worldwide, including Japan, Southeast Asia, South Asia, East Asia, and other regions.
 It was created to celebrate the birth date of Atom/Astro Boy (as well as the 40th anniversary of the original TV series).
 Under the original English name (instead of "Mighty Atom"), it kept the same classic art style as the original manga and anime, but was revisioned and modernized with more lush, high-quality, near-theatrical animation and visuals.
 It combined the playfulness of the early anime with the darker, more serious and dramatic Science fiction themes of the manga and the 1980 series.
 The anime broadcast in Japan on the same date as Atom's/Astro's birth in the manga (April 6, 2003) across Animax and Fuji Television.
 It was directed by Kazuya Konaka and written by Chiaki J. Konaka at the beginning of the series.
 Other writers included were Keiichi Hasegawa, Sadayuki Murai, Ai Ohta, Hirotoshi Kobayashi, Kenji Konuta, and Marc Handler, who was also executive story editor.

Rogier van der Weyden (] ) or Roger de la Pasture (1399 or 1400 – 18 June 1464) was an Early Netherlandish painter whose surviving works consist mainly of religious triptychs, altarpieces and commissioned single and diptych portraits.
 He was highly successful and internationally famous in his lifetime; his paintings were exported – or taken – to Italy and Spain, and he received commissions from, amongst others, Philip the Good, Netherlandish nobility and foreign princes.
 By the latter half of the 15th century, he had eclipsed Jan van Eyck in popularity.
 However his fame lasted only until the 17th century, and largely due to changing taste, he was almost totally forgotten by the mid-18th century.
 His reputation was slowly rebuilt during the following 200 years; today he is known, with Robert Campin and van Eyck, as the third (by birth date) of the three great Early Flemish artists ("Vlaamse Primitieven" or "Flemish Primitives"), and widely as the most influential Northern painter of the 15th century.
