These are 2 different versions of the 3D glasses that were handed out in movie theatres for Freddy's Dead. These were from an estate sale of a man who owned a Drive in theatre and kept all the extra he had at the end of the films run.  There were a total of 5 different versions of the glasses made. This youtube video shows a good story on them!!!! Glasses come in a basic envelope with ear pieces folded.
