In my opinion,
It's NOT rare.
It's not a collectible.
It's not valuable.
It's most certainly not antique. Antique is 100 years or more. This might have been 1950s, and I'm giving it a lot of leeway. It could have been made last week, in India.
I think the seller subscribes to the theory that there is a sucker born every minute. Don't buy it.
