The centre for the first time exhibited little-known graphic works of the two 20th-century acknowledged artists, brought from private collections of France and the United States containing etchings, lithographs and drawings, some of which illustrate creations of play-writers Marquis de Sade and Fernand Crommelynck, according to organizers.
