This ad always reminds me of "Yours Mine and Ours" (1968) with Lucille Ball as the mother of 12. The first time I saw this movie, my heart leapt at the sight of her basement laundry. Two sets of Maytags!
35 loads a week, ~ 14,000 loads in eight years. Washing diapers for more than a decade.
Grandmother's family had 11 children. They carried water from a well to wash by hand on a washboard.
It was likely replaced in 1974 with an LAA5800 when the transmission started leaking so much oil on the belts and they got tired of doing twice as many loads to get all that laundry done.
