When I was a small child visiting my great aunt, I was given this.
It is a bag made out of a Purex bottle and crochet.
When opened, it turns into a bassinet.
Inside the bassinet were two hard plastic babies (marked "Hong Kong") in crocheted outfits. One was a girl, in a dress.
The other was a boy in a bottom and short top. Unfortunately his clothes, both their legs, and the boy's arms are long gone.
They also had a tiny crochet blanket.
I'm not sure if my great aunt made the set herself, or if she purchased it. Either way, it was well loved and a much appreciated gift.
