Recently closed at The Tate Modern is the show: Rodchenko & Popova: Defining Constructivism.
Hard not to like those big block letters on a field of flat black or red.
It reminded me of the Russian Contructivist Show at Walker Art Center in 1990. I was standing behind a man and a woman. They were looking at an advertising poster by Rodchenko, when the man turned to her and said, with some pride, “We can do that at our shop.”
