Up for auction is 1 diaper (only one), a vintage Panty Slip Step by Step baby diaper for girls size Maxi Plus from Greece.  The diaper has a crinkly soft plastic outer covering and is designed to fit babies 9-18 kg or 20-40 lbs. For size comparison, I have taken a picture of one next to a vintage Luvs size 6 diaper for reference.  These are very rare and would be a great addition to someone's collection.  Thanks for looking!
