These were the first uniform Commonwealth stamps issued in Australia, replacing the
Colonial (or State) issues, although the early design stamps (Colonial or State Issues)
remained valid for postage until February 13th 1966. The "Kangaroo" issue was in use
until 1950, being then replaced by the "Coat of Arms" issue for the high values and the
King George VI issue for the lower values.
The Kangaroo & Map series was designed by William Blamire Young, from an idea by the
Postmaster General, Mr Frazer, along with a stamp design competition entry called "Baldy"
(the Kangaroo) by Edwin A. Arnold of London.
This stamp design was released over a number of years in different shades, colours and
values, the years of release were 1913, 1915, 1916, 1917, 1918, 1919, 1920, 1921, 1923, 1924,
