Carte ethnographique de la Russie occidentale et des pays limitrophes en Pologne et en Galicie, 1916

Paris (?), published by J. Bermeiseffimp. Three detail images: the table of populations, the area of the former Grand Duchy, and the legend. The table appears to be based on the 1897 Russian census, but excludes Suvalkų g., where Lithuanian-speakers comprised 52% of all. The mapmaker mistakenly colored that gubernia as Polish-speaking, but colored the Vilnius area as Lithuanian-speaking.
