If it was cheaper I would not hesitate to buy it just for the uniqueness of it alone! It's a gamble, but on the off chance it could be a former prop that got passed through too many hands and ended up as a daily use cleaner, it could well be a prop. You cannot use name brands on most TV shows or movies, and with that big "ELECTROLUX" on the side, that wold have to be changed to avoid the licensing fees.
Who knows where or when. A prop doesn't have to be tidy if it's only to be used for 10 or 15 seconds screen time. Johnny Carson loved to use props on his show and a lot of them were crudely made and just slopped together in 10 minutes to talk about or use as a punchline for a joke, then away it went to be thrown out or in the prop warehouse.
Those decals are period-applied based on the flaking and cracking on them, also it looks like it had two generations of the lettering applied based on the fading, with one set being bigger. It's also only on one side, so if it was sitting on a shelf as a background prop behind a character or something, you would only see the side facing the camera.
Needs more research.
