:As already clearly explained, Italian East Africa  the actual topic of the article  ended years after the start of the U.N. trusteeship of the former Italian Somaliland; Italy was just assigned by the UN to administer the territory as a Trustee, not as a colony. The trusteeship period, in turn, began after Britain (not Italy) maintained the former Italian Somaliland. That means the flag of Somalia (which was created in 1954 by Mohammed Awale Liban, likewise well after the end of Italian East Africa) unfortunately has no place in the article.
