The Beautiful Safe of Harry Isatis is a 142 years old piece made by Harry Isatis, a banker living in Cologne.
Considering its age and the quality of the work, people consider it of little value.
It is engraved with european patterns and some symbols pertaining to Calvinism.
This piece doesn't exist, but as a legend. It is said that in the year 1942, Jacques Isatis, the owner, made use of it in Cologne to empower the Isatis family. Now it is lost, or broken, we will never know.
