I found this in an estate collection of first day covers I got... the person that used to gift subscriptions must have sent this card to the original owner.. All the fdc's were from 1975 so I am assuming that's what year it is from as there was nothing else in the collection from any years other than between 1974 and 1976.

Pre-owned and used. Interior is written in. See photos. Still a great original Hallmark cards from the 1970s.
