Kathleen's sister - Aunt Ruthie - visited their brother Cecil Farmer in Pittsburgh, and sent a postcard to each of her four nephews and nieces. This is the one she sent to Kay, who was not quite four years old (and still known as Kathleen). Maybe Ruth thought the cars in the picture would appeal to a three-year-old.
Ruth didn’t sign the postcard, but it must be from Ruth.
This is one of five postcards that Ruth sent to the four little Stokeys all at once when she was visiting her and Kathleen’s brother Cecil Farmer. Apparently she wrote four of them out on September 6 but couldn’t mail them out until the 7th, and for some reason that impelled to her to write an extra one to Billy on the 7th. Maybe she had made him a promise of some sort? And since Roger was only 19 months old, his postcard was addressed to Kathleen, with a note that once Kathleen had read it, it was to go to Roger.
