Set - 3 books. Complete cycle "ВОЛШЕБНИК ИЗУМРУДНОГО ГОРОДА" (This is the russian version of Frank Baum's “THE WONDERFUL WIZARD OF OZ”) Published in 1985-87 in the Soviet Union.  Five sequels: Urfin Jus and his Wooden Soldiers , The Seven Underground Kings , The Fiery God of the Marrans , The Yellow Fog , and The Secret of the Abandoned Castle. These sequels were written by Volkov himself and are not based on Baum's plot elements, although we do encounter the powder of life, a character called Charlie Black who is not unlike Cap'n Bill , intelligent foxes, and the use of a Sandboat similar to Johnny Dooit's , albeit with wheels. Many color illustrations. Artist - L. Vladimirsky. Condition of the books - very good!
