Millennials don't get to say "Hey! There's MY Mom!", and likely unaware maybe Grandmother instead.

In fairness, her forte before this was NOT a war plant, or production of any kind. After sewing her fingers together making Lipton Tea bags........but a terrific Marine photographer! They addressed her as Babe, never mere babe.

I copied a couple of pictures from that article to show the resemblence to the rubber "boats"
