Identification of kid's bike

[Eophyllis]

Hello, I found this little bike with training wheels. I'm not sure how old it is, but it has solid rubber wheels, heavy metal frame and is very small, like for a toddler maybe? It's very rusty and missing one of the handle bar grips. I don't have an actual use for it, so I'm trying to decide whether to clean it up and display it somehow or sell it. I've heard cleaning up an antique is a bad idea if you want to sell as it lessens the value, is that correct in this case? Thank you for any help.

Schwinn Lil Tiger,circa 1972 or so.the chrome might clean up a bit.paint is marginal in spots.these in good condition can fetch a few hundred bucks.yours maybe 150 or so.
