Having once served for a short time as the interim White House, the officially historic building that now serves as the Arts Club of Washington is about to open a historic, nonoffical exhibit of nonconformist works by modern Russian artists. All of them done within the Soviet Union, mostly in this decade, these paintings will be the first comprehensive look at recent Soviet nonconformist art seen in this country, in fact, few of the paintings have ever been shown outside the Soviet Union. They stretch from abstract expressionism to surrealism to conceptual art. And the show, co-sponsored by the Arts Club and the Cremona Foundation, will spill over to the Kiplinger (Editors) Building, which will display the larger works, the graphics and works in series. None of the works will be for sale, but three local commercial galleries (Jane Haslem, Rowe House and B. David) will be selling similar works in conjunction with this exhibit.
