Through his visionary yet challengingly simple painting, Lundquist became one of the most significant artists of his generation. He represented Sweden at the São Paulo Biennial, where he won an award, and was selected to participate in the Guggenheim International Award in New York in 1964 for the world's 100 best artists, as well as at the Dunn International at the Beaverbrook Art Gallery in Canada and at the Tate Gallery in London.

International museums purchased works by Evert Lundquist, and prominent international galleries wanted to exhibit him, but he decided after a few years to withdraw from the international art market. From 1953, he lived and worked in a white-plastered building at Drottningholm Palace.

A few years before his death, he became completely blind, yet continued to paint until the very end. The house has been preserved as Evert Lundquist's studio museum.
