Bart de Roo purchased a painting of Michiel de Ruyter for €2,700, which has been authenticated as a genuine work by Ferdinand Bol, potentially worth €500,000. The painting includes hand-written labels indicating prior ownership linked to Bol. After thorough examination by experts, De Roo plans to sell the artwork, hoping it remains in the Netherlands, possibly for display in local museums. It will be featured at the PAN Amsterdam art fair next week.
