I have doubts whether the authors were experts The map looks rather like a propaganda picture than a serious work especially if we take into account that it was made during WWI It is indeed misleading since for example Timi oara had 32 097 Germans and 27 189 Hungarians vs the 16 047 Romanians in 1920 still this map colors the town with dark brown i e the color of territories with Romanian inhabitants even though it also presents territories inhabited by Germans and Hungarians dark and light orange An obvious solution would have been to use mixed colors or scales etc but no this map used the same color for Timi oara as it did for e g Bucharest That s quite dubious
