The Scott Stamp Atlas  describes Ireland as an "[i]ndependent state since 1921 (previously part of Great Britain with the exception of six counties in Northern Ireland) …which remain British. In 1937 a Republican Constitution was proclaimed within the British Commonwealth of Nations but in 1949 the independent republic left the COmmonwealth. " The Irish Free State was renamed Eire in 1937.
The first stamps were GB issues overprinted "Provisional Government of Ireland " in Gaelic. The initial set of overprints was made by Dollard Ltd in black or grey and measuring 15x17½mm. There were other overprints later in 1912 in other colours and overprints by Harrison & Sons measuring 15¼x17mm and Alex Thom & Co. measuring 14½x16.
The first dedicated set was issued in 1922-23, the 2d value first and the other values in 1923. The map on the 2d stamp caused some controversy as it showed the whole island without distinguishing Northern Ireland.
