This map was recently featured in an episode of Map Men covering Soviet cold war cartography. It shows southeastern British place names spelled phonetically to teach would be Polish invaders how to pronounce them.
The map was originally put on Twitter by former Economist researcher Alex White but the original tweet appears to be gone. The image above is via The Sun. Some fun names include Saufend-on-Sji (Southend-on-Sea), Hejstynz (Hastings) and Byszeps-Stofed (Bishops Stortford).
A bit shocking to think about perhaps but it makes for some nice wall art
