Old spoon made of German silver.
Fingerprints were found on it, which age is at least 10 years, the person who left them, died 10 years ago.
Just an example how long the #fingerprints could be stored and longer under ideal conditions as a smooth metal surface.
Wiped then with effort, I made a photo for me to collection.
На старой ложке из мельхиора обнаружены отпечатки пальцев, возраст которым не менее 10 лет
