When I, in his time, looking for information about Lisitsky, found that during the "vanguard" (10-20 or even 30's) in Kiev was established and there was an organization called "Cultural League. It was not a purely artistic organization, but rather, the organization popularized the idea of Jewish and Yiddish. (They even opened their representative offices in Moscow, St. Petersburg, etc.) at different times in the range of this organization included, or to cooperate with it, many artists of Jewish origin, in addition to the known (Chagall, Lissitzky, Rybak, Epstein, Rabinovich, Mane-Katz) was still a lot of good artists, which is now almost nothing is known.
