Until recently, licensed collectors were able to travel to Cuba and bring some art back to the United States. But “the Bush administration has canceled most licenses for culture-related Cuban travel, and the Treasury Department recently stepped up prosecution. Americans who are caught taking unlicensed trips to Cuba from, say, Canada or the Caribbean now face hefty fines, reportedly up to $10,000. The Cuban government allows some artists to leave the country to sell their work, and Cuban artists may mail works to the United States. But some Cuban artists at the Havana Biennial were worried they might have trouble obtaining U.S. visas to attend gallery shows here.”
