What is the 1977 edition of The Rubaiyat of Omar Khayyam printed by Shumposha Photo Printing (Japan) worth?

This book has 50 plates in color by the Iranian artist Hossein Behzad Miniature. It features the English translation of Edward Fitzgerald. It is in Persian, English and Armenian. The Editor for the 1949 edition was Dr. H.A.N Esfandiary. I would appreciate any information on its value. As well, I would like to know a little about the process of photo printing. The illustrations are stunning.
