Russia is a very big country. West of the Ural Mountains is West Russia, with the rest tacked on almost as an after-thought, filling the second side. Most of the population is concentrated in the West, necessitating a better scale to provide enough space to note the many cities and the road/rail network.
Most visitors fly into Moscow, then travel by train to other cities, primarily within the Russian heartland. Many also embark on the Trans-Siberian Railway, which necessitates the second side of the map sheet. This side covers the vast expanses of taiga and forest from Perm east to Vladivostok—a journey that takes about a week by train. Theoretically, this portion of Russia is drivable if weather conditions permit. Geographically, this area is much larger and can only be shown at a somewhat reduced scale.
For those wishing more detail, ITMB also publishes maps of Siberia and the Far East Republic/Kamchatka Peninsula, as well as its famous road/train atlas of the Trans-Siberian rail network.
Russia is not the easiest country to enter, but once there, it is an unforgettable experience.
