The painting, Night of Jealousy, is valued at 10 million kronor ($1.6 million). It was found wrapped in cloth in a suburb in the northern outskirts of the capital.
“On first viewing the painting does not appear to be damaged. There is also every indication that it really is the stolen painting,” museum director Stefan Bohman told UNT.
Strindberg made the painting in Berlin in 1893 as a gift to his then fiancée Frida Uhl.
