It is true!

The ears are part of the Mary Jennara Wenk Star Trek Collection (MsC1031) and the individual item listing in ArchivesSpace can be found here.

From the listing if you select "Aeon Request" in the upper right corner of the screen you can put the object on hold in the Special Collections reading room and pay a visit to see them yourself!

Here is a brief rundown of visitor policies for Special Collections & Archives (open to the public Monday through Friday!), and as always if you have additional specific questions don't hesitate to reach out directly.
