 In the 19th century a painting that came to be known as the Flower portrait was discovered , inscribed with the date 1609 and painted on an authentic 17th @-@ century panel . It was initially widely accepted as the original work from which Droeshout had copied his engraving , but in 1905 the art scholar Marion Spielmann demonstrated that the portrait corresponded to the second state of Droeshout 's print . Taking the view that if it were the source , the first state would be closest , he concluded that it was a copy from the print . In 2005 chemical analysis proved the portrait to be a 19th @-@ century fake painted over an authentic 17th @-@ century image .
