Exhibition "Russian Avant-Garde in Moscow Today," Cologne (30.01 - 25.03. 1970), at the "Gmurzhinska" gallery.

"One of the most important representatives of contemporary avant-garde art in Moscow, whose imagination is akin to late European surrealism," - this is how it was written in a small exhibition catalog, where two works by Ülo were published.

In total, there were 19 works by Sooster presented at the exhibition in Cologne.
