Vintage key fob or watch fob piece from I believe the 1970's.  My friend was in the construction business at this time.  Heavy duty construction.  Measures 1-3/4" x 1-3/8".  Believe it is brass.  Marked on back:  CANADA.  Front has three construction vehicles including a scoop and a crane.  HIGHWAY EQUIPMENT CO Pittsburgh  Erie  Dubois.  Nice shape. Not on a band so it was probably never used.  I do combine shipping and use recycled packing. From a clean and dry, non-smoking environment.
