Ary Murnu was a Romanian caricaturist, picture story artist and stamp designer during the first half of the 20th century. He was born Arytomene Gheorghiadis Murnu in Greece into a family of Macedonean-Romanian origins. Both he and his brother, writer and translator George Murnu, began their careers upon their arrival in Romania in 1905 with contributions to the anti-monarchy magazine Furnica.
Murnu was an illustrator with the weekly children's magazine Lumea Copiilar between 1922 and 1925. During this period he also made picture stories with a moralistic tone. He designed five series of postcards with Carol II for the Romanian Postal Services from 1930 to 1934.
He returned to the comics genre in 1936 with stories like 'Nică, Tică şi Lică' and 'Păcală şi Tândală' for Lumina Copiilor. When the magazine folded in 1938, Murnu turned to painting and book illustration. He has illustrated many books that were either written or published by his brother. He designed new sets of postcards between 1943 and 1949, that are highly praised among Romanian stamp collectors. Ary Murnu retired in 1949 and passed away in Bucharest in 1971.
