In the 1950s it wasn't uncommon to sell things from the home. Wives did not work then, and to make pin-money would sell eggs or piano lessons, or like my mother, sewn goods. My brother and I, ten and eight respectively, would cart a small suitcase loaded up with a dozen or so aprons and a sales book, and go door-to-door.
This design of this apron is based on measurements from one my mother made in the 1950s for us to sell. I think you'll find it just as useful today.
Now I have made My Mother's Apron with a full bib style.
