Lukomorye. The illustration, based on the famous russian tale.

"An oak tree greening by the ocean;
A golden chain about it wound:
Whereon a learned cat, in motion
Both day and night, will walk around;
On walking right, he sings a ditty;
On walking left, he tells a lay.

A magic place: there winds his way
The wood sprite, there's a mermaid sitting
In branches, there on trails past knowing
Are tracks of beasts you never met..."

This is a most known fairy tale of A. Pushkin, which is based on russian folklore.
