This is the original cover painting for the fictional historical novel by James A. Michener, published by Corgi, 1980.  A gorgeous scene, stunning visual - and Pether gave it his all, with dimensions of 13" x 22" - which Corgi of course obliterated with the format chosen for its line of Michener paperbacks!  Painted gouache and acrylic on illustration board, and comes with a label attesting to its authenticity signed by Pether's widow, mounted to the back.  There are other covers for Michener novels - inquire if interested - but none like this one  - one of the best - so if you love it, don't hesitate.
