The above photo (A. Aubrey Bodine) came from a Baltimore facebook group. It shows women cutting corn off the cob probably for a canning company. It looks to be maybe in the 1930s or 1940s.
What is interesting the women seem to be wearing a breastplate with a spike thru it, on which the corn cob is stuck and then she uses a knife to remove the kernels. Looks like after a full shift of that the woman would be black and blue. Well no one said life was easy and she no doubt is just happy to earn the small amount of money she would receive.
