One of those rare cards that assumes you know where such a place is, so doesn’t tell you.  We didn’t know, so we looked it up.  Unless there are two with the same name, this is in Vermont.  Dexter Press card 46459-C (and V-3684) has serrated edges and was mailed in 1973 with 8-cent Osteopathic Medicine stamp and full postmark.  Grade: 1
