Phrenology bust research

Today I observed people researching a Phrenology bust. They first made their observations, then they started researching on their computer. They started of using search terms such as " Phrenology and Phrenology Bust." Then they went on to start researching the years they were made. One person in my group rescued all of the writing on the Bust, while the other person researched how to tell if it was a real Phrenology bust. We learned that these are no longer in use and that the one we were observing was not real, but a replica. Provenance- the place of origin or the earliest know history of something.
