A painting by American artist Jacob Lawrence that has not been seen in public for 60 years has been found and is taking its designated place in a 30-piece exhibit of Lawrence’s work, officials at the Peabody Essex Museum in Massachusetts said Thursday.

The exhibit of the series “Struggle: From the History of the American People,” completed in the mid-1950s by the Black painter, was organized by the Salem-based museum and is currently showing at The Metropolitan Museum of Art in New York City, with the missing piece — known as panel 16 — represented by an empty frame.

The existence of the missing panel was known through a brochure that accompanied the first showing of the series in New York in 1956

Even with the discovery of panel 16, four panels remain unaccounted for, according to the Peabody Essex Museum
