Problem: Background: N. T. Rama rao (NTR) was born on 28 May 1923 in Nimmakuru, a small village in Gudivada taluk of Krishna District, which was a part of the erstwhile Madras Presidency of British India. He was born to a farming couple, Nandamuri Lakshmaih and Venkata Ramamma, but was given in adoption to his paternal uncle. He attended school at first in his village, and later in Vijayawada. After his matriculation in 1940, he studied at SRR & CVR college in Vijayawada and at the Andhra-Christian College in Guntur.
Context: NTR started his film career with a walk-on role as a policeman in Mana Desam (1949). Following this, he appeared in Palletoori Pilla, directed by B. A. Subba Rao. His first mythological film was in 1957, where he portrayed Krishna in the blockbuster film Maya Bazaar. He essayed the role of Krishna in 17 films, including some landmark films such as Sri Krishnarjuna Yudham (1962), the Tamil film Karnan (1964) and Daana Veera Soora Karna (1977). He was also Known for his portrayal of Lord Rama, essaying that role in films such as Lava Kusha (1963) and Shri Ramanjaneya Yuddham (1974) to name a few. He has also portrayed other characters from the Ramayana, such as Ravana in Bhookailas (1958) and Seetharama Kalyanam (1961) among others. He portrayed Lord Vishnu in films such as Sri Venkateswara Mahatyam (1960) among others and Lord Shiva in Dakshayagnam (1962). He has also enacted the roles of Mahabharatha characters, such as Bheeshma, Arjuna, Karna and Duryodhana.  Later in his career, he stopped playing the role of a prince in his commercial films and began to play roles of a poor yet heroic young man fighting against the existing system. These films appealed to the sentiments of the common man. Some of these films are Devudu Chesina Manushulu (1973), Adavi Ramudu (1977), Driver Ramudu (1979), Vetagadu (1979), Sardar Papa Rayudu (1980), Kondaveeti Simham (1981), Justice Chowdhary (1982) and Bobbili Puli (1982). He also portrayed fantasy roles, his notable film in that genre being Yamagola (1977). His film Lava Kusa, in which he starred as Rama, collected 10 million rupees in 1963. He directed and acted in the hagiographical film Shrimad Virat Veerabrahmendra Swami Charitra (1984). He also acted in films such as Brahmasri Viswamitra (1991) and Major Chandrakanth (1993). His last film was Srinatha Kavi Sarvabhowmudu, a biopic on the Telugu poet Srinatha, which released in 1993.  In the later half of his career, NTR became a screenwriter. Despite having no formal training in script writing, he authored several screenplays for his own movies as well as for other producers. He also produced many of his films as well as other actor's films through his film production house National Art Theater Private Limited, Madras and later Ramakrishna Studios, Hyderabad. He actively campaigned for the construction of a large number of cinemas through this production house. He was influential in designing and implementing a financial system that funded the production and distribution of movies. He was so dedicated to his profession that he would often learn new things in order to portray a particular character on-screen perfectly and realistically. At the age of 40, he learnt dance from the renowned Kuchipudi dancer Vempati Chinna Satyam for his role in the film Nartanasala (1963).

Problem: Background: Jean-Michel Basquiat was born in Brooklyn, New York, on December 22, 1960, shortly after the death of his elder brother, Max. He was the second of four children of Matilde Andrades (July 28, 1934 - November 17, 2008) and Gerard Basquiat (1930 - July 7, 2013). He had two younger sisters: Lisane, born in 1964, and Jeanine, born in 1967. His father, Gerard Basquiat, was born in Port-au-Prince, Haiti, and his mother, Matilde Basquiat, who was of Puerto Rican descent, was born in Brooklyn, New York.
Context: "Basquiat's canon revolves around single heroic figures: athletes, prophets, warriors, cops, musicians, kings and the artist himself. In these images the head is often a central focus, topped by crowns, hats, and halos. In this way the intellect is emphasized, lifted up to notice, privileged over the body and the physicality of these figures (i.e. black men) commonly represent in the world."  Fred Hoffman hypothesizes that underlying Basquiat's sense of himself as an artist was his "innate capacity to function as something like an oracle, distilling his perceptions of the outside world down to their essence and, in turn, projecting them outward through his creative acts." Additionally, continuing his activities as a graffiti artist, Basquiat often incorporated words into his paintings. Before his career as a painter began, he produced punk-inspired postcards for sale on the street, and became known for the political-poetical graffiti under the name of SAMO. On one occasion Basquiat painted his girlfriend's dress with the words "Little Shit Brown". He would often draw on random objects and surfaces, including other people's property. The conjunction of various media is an integral element of Basquiat's art. His paintings are typically covered with text and codes of all kinds: words, letters, numerals, pictograms, logos, map symbols, diagrams and more.  A middle period from late 1982 to 1985 featured multi-panel paintings and individual canvases with exposed stretcher bars, the surface dense with writing, collage and imagery. The years 1984-85 were also the main period of the Basquiat-Warhol collaborations, even if, in general, they were not very well received by the critics.  A major reference source used by Basquiat throughout his career was the book Gray's Anatomy, which his mother had given him while he was in the hospital at age seven. It remained influential in his depictions of internal human anatomy, and in its mixture of image and text. Other major sources were Henry Dreyfuss' Symbol Sourcebook, Leonardo da Vinci's notebooks, and Brentjes' African Rock Art.  Basquiat doodled often and some of his later pieces exhibited this; they were often colored pencil on paper with a loose, spontaneous, and dirty style much like his paintings. His work across all mediums displays a childlike fascination with the process of creating.
Question: When did he start selling the postcards?
