トリエステ自由地域
The 1947 Peace Treaty established Trieste and the surrounding area as the Free Territory of Trieste, also divided into zones A and B, under Allied military administration and Yugoslav military administration, respectively. In Zone B, stamps inscribed "STT VUJA" ("Free territory of Trieste, Military Administration of the Yugoslav Army") were issued. The Free Territory was divided between Italy and Yugoslavia in 1954, with Zone B joining Yugoslavia.
