I can't express what a great series this is. I am always "glued" to most British TV series (e.g. Hercule Poirot, All Things Great and Small) because of the acting and of core the period detail. However, this American series is exceptional. However, I must warn everyone that there are truly "gory" (lots of blood) scenes.
I added the listing below because of the box. I also like old type and artwork.
Sometimes the artwork can help in zeroing in on the approximate date that the toy was made.
