Once again a collector’s dream has come true. A retired doctor from a remote town has discovered his father had a collection worth millions and he could sell it. The doctor went to a Paris auction house and showed them 14 ink drawings. One 7 1/2-inch by 5-inch piece of paper with a sketch on each side was interesting. The auction house’s expert on old master paintings realized the drawing might be from the 16th century. Three months and three art experts later, the sketch has been authenticated as the work of Leonardo da Vinci, drawn about 1482-85. The handwriting, inscription, and the subject are all related to a known drawing of St. Sebastian by da Vinci. The good news for the owner is the sketch is estimated at about $15.8 million. The bad news is that the French government has put an export ban on the art work because it is “a national treasure.” The owner would like to offer it to an international market where it could sell for much more. The French government has 30 months to buy the sketch at market value.
