Visionary architect and artist Iakov Chernikhov (1889 – 1951) produced gorgeous conceptual architectural renderings that were years ahead of their time; his designs bore remarkable resemblance to the modernist architecture of the late 20th century. These images are from his seminal 101 Architectural Fantasies, published in 1933.
I love constructivism. Partly it's the color schemes; partly it's the architecture. This is by Iakov Chernikov.
