The museum in the city of Siegen (North Rhine-Westphalia) in Germany is convinced that Rembrandt found etchings in its archives.
This work is part of a larger collection of paper-based works of art that have been owned by the Siegerlandmuseum since 1991. Etch caused by Rembrandt was investigated by unknown producers.
Ursula Blanchebarbe, the museum's chief, says he does not question authenticity. During the etching process, a painter of the seventeenth century described the famous Amsterdam writer and Lieutenant Professor Lieven Willemsz of Coppenol, who he often portrayed.
The museum removed the etch from the shop and displayed it.
