The CBS Spl tonight of the 'I Love Lucy' Christmas show had a good shot of Lionel trains! You could tell it was a product placement or whatever they called it back then as the train was set up on the floor and the big yellow 'LIONEL' box was upright behind the layout.....and Ricky was setting it up before little Ricky got up. Don;t know my 1950 era Lionel to rtell what set it was....sure someone here will....
Just shows how important Lionel was mid 50's.
