A Rembrandt expert is challenging London's National Gallery to reexamine a 17th century painting deemed not to be by Rembrandt. The museum purchased Old Man in an Armchair in 1957, but ruled in 1969 that it was not by the Dutch master. Professor Ernst van de Wetering, director of the Rembrandt Research Project, believes it to be real, and an important showcase of the painter's experimentation with his craft at the time.
