I will share a little nostalgia.
Here is the Split Level Home again:
My Aunt Ruth lived with her family (my Uncle Bill and 3 cousins) in a gorgeous sprawling split level home in Pennington, NJ. I spent a good portion of my summer vacations there when I was growing up, and I was treated like a prince there. This split level model reminds me of Aunt Ruth's Pennington, NJ home.
Incidentally, Aunt Ruth may have given me my original Plasticville Split Level home as a Christmas gift, together with the many Lionel trains and accessories she gave me as Christmas gifts. She loved Lionel trains, and helped my cousin Billy with his gorgeous Lionel train layout in the basement, including making the mountain and tunnel on it.
