The superbly rendered, playful black and white illustrations of Gennady Kalinovskii have up to now only been available in editions by Detskaya Literatura published in Moscow: Wonderland in 1977, retold and introduced by Boris Zakhoder, and Looking-Glass in 1980, retold and introduced by Vladimir Orel. The publisher Studio “4+4” from Moscow has recently reprinted them in a larger art edition (21.5 cm x 32.5 cm vs. 17 cm x 22 cm), with paper board and cloth binding. They can be ordered (in English) directly from the editor, Elena Borisova, for $90 for both books, including postage, at firstname.lastname@example.org. The books can be mailed anywhere.
