The Historic Hat of Esmeralda Mansagil is a 154 years old piece made by Esmeralda Mansagil, a crime lord living in Lisbon.
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 Folk religion.
This piece doesn't exist, but as a legend. It is said that in the year 1975, Augustus Mansagil, the owner, made use of it in Lisbon to empower the Mansagil family. Now it is lost, or broken, we will never know.
