WARSAW (AP).- It’s finally been decided: Poland’s most precious painting, “Lady with an Ermine” by Leonardo da Vinci, will be allowed to travel to Spain, Germany and Britain. Wednesday’s decision came after almost a year of discussion by art experts and Poland’s Culture Ministry about whether the 15th-century masterpiece should be allowed to leave the country. Last week, art conservationists warned it could be damaged in transit. Da Vinci painted the portrait of Cecilia Gallerani on a chestnut board around the year 1490. It has belonged to the Czartoryski family in Poland since the early 19th century.
