Context_1 : Hernando Osorio (born 1953 in Ibague, Colombia) is a painter and print-maker. Educated at the National University of Colombia, he was a member of the Awuyaka street art group. During his New York City period (1981-1985) he focused on etching and lithography. Since 1985 he has been living and working in Vienna, Austria. His preferred techniques are mixed-technique painting on canvas, woodcuts and linocuts but he has also made paper, produced hand-bound books, and recently created a series of ceramic plate images. His work reflects his concern for wild life, the role of the human being in nature, and traditions of folk art across the world. Context_2 : Surrend: Arts in hotspots is the name of a Danish street art group consisting of artist and teacher at the Royal Danish Academy of Art "Jan Egesborg" and artist and journalist "Pia Bertelsen". Context_3 : Roman Tyc (David Hons by his own name) (born 1974) is a Czech artist known for his guerrilla art work in "public space" or "street art". Tyc is a co-founder of the "Ztohoven" art group and of the visual art group "PureA". He helped with the formation of alternative culture centre "Ateliery Trafacka" (Trafacka studios). Context_4 : Felipe Cardena is a very well known artist that nobody has ever seen. The newspaper "Corriere della Sera" wrote on May 2008: "We only thing we know is that he was born in Balaguer, Spain, 29 years ago. The rest of the information we have regarding Felipe Cardena, mysterious artist Banksy's style, is fragmentary and contradictory. His floreal collages whose technique was probably developed in jail and his floreal stickers appear everywhere: his slogan is Power Flower"(1). Maybe behind Felipe Cardena's identity there is a collective of artists with different backgrounds and origins, probably related to the street art world. Certanly one of the first exhibitions where he appeared was in the 2005 in Milan, Miracolo a Milano (2), by acting as the statue of St John the Headless, and where he stood without a single movement for six hours. In 2007, he put the pirates flag right at the entrance of the exhibit Sweet Art Street Art as the symbol of street artists who fought and won over the Padiglione d'Arte Contemporanea, in Milan. Eventually, his art work was stolen by one of the visitors. Since the end of 2007 he started the project "Power Flower". In 2008 Felipe Cardena prepared a gigantic panel to be shown at the street art exhibit Scala Mercalli, dedicated to the Dalai Lama. "Free Tibet Free Flowers" was written on the panel in capital letters. in 2009 he exposed a giant panel with the portrait of Che Guevara "floreciente" in L'Avana, Cuba, for the Arte Mas 2009, Festival Internacional de arte y Literatura joven. His most recent art work is based on the idea of "surprise" and "astonishment": large sometimes monumental colorful flower compositions, eccentric collages, unusual shapes, strongly exaggerated images underlining the themes of religion and cultural diversity, a mixture of human and natural forms. Context_5 : Chung-Chuan CHENG (, 1931-), a female Taiwanese painter, was born in Hsinchu City.

While majoring in Fine Arts at National Taiwan Normal University, Chung-Chuan Cheng joined the Fifth Moon Art Group encouraged to set up by a painting professor Ji-Chun Liao in 1957.

She not only started to hold solo exhibitions in Japan but also returned to Taiwan for joining annual exhibitions of the Fifth Moon Art Group. Just before her eightieth, Dr. Sun Yat-Sen Memorial Hall staged her art retrospective exhibition in 2011. Besides, a private charity organization also took place a bazaar of her works for the benefit of the mental and physical disabled residents in Hsin-Chu.In 2013, Taipei Fine Arts Museum invited Chung-Chuan Cheng to join the group exhibition "Women Adventurers: Five Eras of Taiwanese Art, 1930-1983".

This project was co-founded by Mia Grondahl, a Swedish street art documentarian, and Angie Balata, an Egyptian artist, in December 2012 with funding from the Danish Center for Culture and Development, and was launched with a month-long event in the Spring of 2013 in Cairo, Luxor, Alexandria, and Mansoura that included painting sessions, workshops, and lectures on topics ranging from art to women's issues more generally.

Lister helped pioneer the street art movement in his home city as a teenager and is considered Australia's premier street artist. His scrawling, figurative style employs charcoal, acrylic, spray paint, and oil. "The first rule of painting is to take everyone else out of the equation," he has said. "I am the viewer, so I don't underestimate my viewers. They see everything and I just have to assume that they are me. I can't paint for anyone else." His exhibitions include those held at the New Image Art Gallery in Los Angeles, Robert Fontaine Gallery in Miami, Jonathan Levine Gallery in New York and Black Art Projects in Melbourne. Lister currently lives and works in Sydney, Australia. Context_8 : The Influencers is a festival that mixes art, guerrilla communication and radical entertainment.
