I found this print when visiting a friends house and fell in love it is by David Koster (1928).
David Koster studied at the Slade School of Art, he is well known for his work with wildlife and is an extremely accomplished naturalist and founding member of the Society of Wildlife Artists. Generally, he works in lithography.
“I find the different print media particularly suitable for the depiction of wildlife, despite the technical difficulties they present and the hard physical work involved. Plus I find the need to make drawn and coloured studies from life and gather reference material a satisfying discipline.” David Koster
