I found these at my parent's home and no longer have the model's that I used to display them in.
I bought them from the Franklin Mint along with some of the Die-Cast cars back in the late 1990's - early 2000's. If I remember correctly, the cases themselves sold for about $40!
These are high-quality display cases. The lower display base is made of wood and the covers are plastic.
They are in very good condition with plenty of dust. I didn't want to clean the clear covers because I didn't want to scratch them.
There are (3) complete cases and (1) base only.
The complete set is offered for one price, $15.
I live just outside of West Jefferson which is off of route 40 between Columbus and London.
Message me through Craigslist and I will give you phone and address.
