Congratulations to reader sandyoppelt! You are absolutely right!
Our mystery artifact photo (above) shows three irons sitting atop an iron warmer on the stove in our Prairie Stories exhibit:
It grew from humble beginnings when Arah Mae Shelton decided that she would bring in washing to support her family. Daughter Frances Shelton Moreland recalled that the employees "were a 'melting pot' made up of Africans, Hispanics, a young man from India (who later married into the family), African Americans, and Caucasians." She said "Mother left us a legacy . . . . She took an old black pot, a washboard, and an old iron and turned it into a multimillion-dollar business . . ."
Many irons, including self-heating models that run on kerosene, and other artifacts from the Shelton Laundry assemblage can be seen on display directly across from the stove and irons pictured above. Come visit us sometime soon and see them all!
