Animal magic - an edition of all ten of Warhol's endangered animals screenprints, from 1983, are going up for auction at Sotheby's on March 19th, with an estimated sale price of £250,000-£300,000. The set  includes a Black Rhinoceros, an African Elephant and a Siberian Tiger. Warhol was commissioned to produce the prints to raise awareness and fundraise, following discussions about environmental issues with New York gallery owners Ronald and Frayda Feldman.
