The Disturbing Sheet of Gilat Martin is a 865 years old piece made by Gilat Martin, a laundry washer living in Baghdad.
Considering its age and the quality of the work, people consider it of some value.
It is engraved with central asian patterns and some symbols pertaining to Rabbinic Judaism.
This piece doesn't exist, but as a legend. It is said that in the year 1401, Jack Martin, the owner, made use of it in Paris to empower the Martin family. Now it is lost, or broken, we will never know.
