NEW YORK — After decades of art auctions and markets being dominated by European and American artists such as Picasso, Degas, Monet, Dali, Rockwell, Wyeth, Warhol and others, the international world began to take notice of Cuban artists in the 1980s. From Havana to Miami and New York, art centers today are continuing to propel established and also up-and-coming artists from Cuba to the forefront.
