"European Russia." This map is from the same plate as the 1914 English-language edition of Baedeker's Handbook for Travelers to Russia. Because we do not have to a high-resolution copy of that particular edition, we are using this 1910 map of the same space. It comes from the following atlas:
The Royal Atlas Of Modern Geography Exhibiting, In A Series Of Entirely Original And Authentic Maps, The Present Condition Of Geographical Discovery And Research In The Several Countries, Empires, And States Of The World By The Late Alexander Keith Johnston ... With Additions And Corrections To The Present Date By T.B. Johnston ... With A Special Index To Each Map. A New Edition. W.& A.K. Johnston, Edinburgh And London, MDCCCXCIII.
