1964 Addams Family Gum and Trading Cards

I always liked the gum from trading card sets, it had an odd flavor that was never present in other gums.  The Addams family card set - complete - consisted of 66 cards.  On the back of each card was part of a photo that when put together made a huge portrait of the family.  I scanned mine as seen below.

I remember going into our local drugstore and asking for the empty display box.  They looked at me like I was a very crazy kid, who would want the box?  I liked it because it was in color and looked very cool with that purple background.  The saleswoman gave it to me, but it was destroyed within a couple years, I wasn't very careful about saving things back then.  The box sells for at least $500 now.
