Warhol produced a series of prints of animals to illustrate `Vanishing Animals?, a book by the German-born, American pathologist and geneticist, Kurt Benirschke. The book has fifteen chapters, each concentrating on one animal of a lesser-known species that was critically endangered. This poster features one of the prints ? a female Douc Langur and its baby. He has incorporated blocks of irregularly shaped colour, which, although screenprinted, appear like collaged fragments of coloured paper. In combining this with hand-drawn lines (also printed), the works appear more expressive than many of his earlier prints. This project (alongside his 1983 portfolio `Endangered Species?) shows Warhol?s awareness of and interest in environmental issues.
