It may not be a glaring mistake, but...
The city today called Zadar, currently located in Croatia. However, during the interwar period, the city was an Italian exclave. Well, in my opinion, since it is a historical map and a small Gigraltar has been made, it is even more interesting if the province was reduced. So, in the attached image I tried to do it as accurately as possible.
Thick white line - new province borders
Thick dark red line - province border to be removed
Thin yellow lines - roads
Yellow background - new Italian province Zara
Blue background - the new Yugoslav Province Gospić
Since Zadar was a city, in order to keep the balance of cities in Yugoslavia, a new one can be made - Split
