(AP) — The Joslyn Art Museum in Omaha is preparing to once again exhibit its original Rembrandt.

The museum plans to open it for public viewing on Tuesday after an absence of around 15 years.

The “Portrait of Dirck van Os” was bought from a private collection in 1942 but was reclassified 45 years later as a painting by one of Rembrandt’s students in the “School of Rembrandt.” It was taken down in 1999 and stored.

The museum said last month that an expert has since examined it and certified it as an original work by the 17th-century Dutch master. It’s been restored to near original condition.

The museum has not provided a monetary value for the painting, but Rembrandts have sold in the tens of millions of dollars in recent years.
