Evald Okas (28 November 1915 – 30 April 2011) was an Estonian painter, probably best known for his portraits of nudes.
Okas was born in Tallinn, where he began his artistic career while studying at the State Art School.
In 1947, Okas, with Elmar Kits and Richard Sagrits painted the ceiling of the Estonian National Opera in the style of socialist realism.
[3] By the late 1950s, Evald Okas was working mainly in the medium of charcoals and earning his living by sketching ex libris - graphic designs that identify the owner of a book, usually pasted onto the inside cover.
Around this time Okas was even given permission to travel; first, within the Soviet Republics, then later worldwide and exhibit works as far afield as Asia and Western Europe.
