Color work on a computer screen give the impression of color lithographs ( large grains , white background , there is no smearing ), black-and- Belarusian Research Institute - engraving on linoleum or plastic. Scenes from the color of Pushkin , and possibly , Gogol , and if the size is small, it can be book illustrations , ie, originals, which are then replicated for the books printed .

The signature on the first three are very similar to the signature of Vladimir Ivanovich Ilyushchenko (b. 1936), he worked very hard in the lottery prints in color lithography technology (if not mistaken, drew on the stone with oil pastels)
