These ladies aren't afraid of a little hard work, and their shoes show it. In the years before large-scale conspicuous consumption, many folks got two pairs of shoes per year: the new pair, often bought around Easter, superseded the old pair as the "good" ones, and the old pair became everyday or "work" shoes.

That's a homemade sun-protection outfit right there. Sunbonnet and sun-shirt in matching fabric.

Lady on the left seems justifiably proud of her flower print ensemble of sun bonnet and jacket.

I am guessing that the head coverings and long sleeve shirts indicate these ladies are heading out for a long day's work in a family field. I am surprised they do not have their ankle high work shoes on. My grandmother, a little older than these ladies in 1940, would have been dressed very similarly for her daily chores outside the house.

Rainbo or Holsum, it's going home to the breadbox, which survived in the kitchen at least until the 1950s' Twenty Questions ("Is it bigger than a breadbox?").

The last couple of images show that in 1940, an entrepreneur could have really cashed in by opening a shoeshine stand in Pinal County, Arizona.

It's time to tear the April page off the Rainbo Bread wall calendar, says the hirsute gentleman mostly out of lens range. Also, got any shoe polish for these ladies?
