What type of gesture does Minority languages of Austria and Austrian State Treaty have in common?
Austrian State Treaty The Austrian State Treaty (German:    ) or Austrian Independence Treaty re-established Austria as a sovereign state. It was signed on 15 May 1955 in Vienna, at the Schloss Belvedere among the Allied occupying powers (France, the United Kingdom, the United States, and the Soviet Union) and the Austrian government. It officially came into force on 27 July 1955.
Irish Sign Language Irish Sign Language (ISL, Irish: "Teanga Chomharthaíochta na hÉireann" ) is the sign language of Ireland, used primarily in the Republic of Ireland. It is also used in Northern Ireland, though British Sign Language (BSL) is also used there. Irish Sign Language is more closely related to French Sign Language (LSF) than to British Sign Language, though it has influence from both languages. It has influenced sign languages in Australia and South Africa, and has little relation to either spoken Irish or English.
