Digital map data 1939-1945

Hello,

I want a tileset that will depict the world as it was during Second World War.  For those who may not know, tilesets are the digital images that represent the map in navigation apps like Google Maps and Waze.  Short reference link: https://docs.mapbox.com/help/glossary/tileset/

Does anyone know if such a resource exists?  If not, I will have to make one myself, which will require prodigious amounts of data for things like the boundaries of countries, roads, topographical information, and more.  If it makes things any easier, I am focusing on the European Theater of Operations for the time being.  Any suggestions or resources would be greatly appreciated!  I want to make exploring historical information as pleasant a user experience as the apps we use every day.
