This is a very nice and detailed map of the expanding Russian Empire.  Finland, the Baltic states, Belarus, Ukraine, Moldova and much of Georgia, save Guria, Armenia and Azerbaijan are part of the Empire.   The 47 provinces are listed in the legend and are color-coded.  Plenty of details are offered as to topography, rivers, lakes, roads, and settlements.  From A New General Atlas of the World.  Teesdale maps are increasingly scarce.
