The Standard Anatomy chart of Cholos Tuiran is a 123 years old piece made by Cholos Tuiran, a doctor living in Barcelona.
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 Lutheranism.
This piece doesn't exist, but as a legend. It is said that in the year 1926, Cholos Tuiran, the owner, made use of it in Barcelona to empower the Tuiran family. Now it is lost, or broken, we will never know.
