Talcum powder with the big puff! My Aunt Mary always had these and would puff us. I think they made a mess as I got older and sold Avon, but as I kid I thought they were so much fun, that big puff was so pretty to me.
Baby in a pram outside getting fresh air with a sun canopy to protect them from the sun. There would often be a "cat net" too, as it was believed that cats would join the baby in the pram and smother it.
