These huge limited edition lithographs are by George French Angas (1822 - 1886). Angas was an English explorer, naturalist and painter who emigrated to Australia.
In 1844 he travelled to New Zealand. He was fascinated by the scenery and Maori life. Angas drew sketches during his journey and kept a detailed journal. He used his sketches to paint New Zealand scenes. These were the basis for lithographic plates published in "The New Zealanders illustrated" in 1847. Few were made and nowadays this work is very rare. In 2009 a set was sold by Christies in New York for US$16,000.
Here are some of lithographs of his work for you to choose from. They are from a limited edition set (only 750 copies were made) made by master printmakers in Japan in 1966.
