The majority of the Black and White paintings  of Maximillien de La Croix were not indexed or catalogued in available art publications. I had to use other means and resources to have access to some of the original artwork of the founder of the PROGRESSIVE NEO CUBISM. Thanks to the assistance of Mrs. Aurele de La Croix, I became able to enter in touch with art collectors who had in their collections, some of Maitre de La Croix’s original Black and White paintings. The task was painful because many of them were living abroad and in far distant countries and cities such as Cape Town, Lima, Buenos Aires, Omsk, Kiev, Odessa, Tblisi, etc.
