Translated from Dutch daily De Volkskrant today:
For thirty-five years, Geurt Imanse has worked for the Stedelijk Museum in Amsterdam, but he never discovered such a find. In a depot of the museum he found an unknown drawing of Russian artist Kazimir Malevich (1879-1935), one of the founders of abstract art. The Stedelijk manages the largest collection of Malevich works outside of Russia.

What makes the discovery even more beautiful: the small sketch, 14 by 10 centimeters, is a preliminary study for An Englishman in Moscow, a famous Malevich painting from 1914, which is also in the collection of the Stedelijk. No preliminary study was known of that work. …
The sketch and the painting An Englishman in Moscow, according to the Stedelijk Museum, belong to Malevich’s “a-logical” work, in which reason had to be ruled out in painting. It was a first step towards his new style, the abstract suprematism. The text on the preliminary study and the painting reads: ‘Partial eclipse’. According to Malevich, a solar eclipse was required. The old aesthetics had to disappear. The drawing will be visible to the public from the 2nd of June on in the museum.
