This is a Lionel promotional record that you could get in the 1950's. This one was an uncatalogued special request item that features a small 78 rpm record with STEAM AND DIESEL sound effects. There are a few small waves here and there but they are minor. They can be pressed flat, unlike thicker vinyl. However, if this one will be on the wall or in the case, it does not matter because it looks GREAT.
This record features vintage Lionel Trains ART with a different scene on each side. And these scenes are some of the most scenic Lionel art I have ever seen.
What a neat looking item for the collector case, "store" display, or framed on the wall.
This would be awesome for your train room or man cave!
You won't find it much cleaner.
