It served a purpose for her. It kept her hair-do - well, done. All of the ladies that came to her salon bought one to keep their "DO's" done until their next hair appt. which was a week later. Same place, same time, week after week, year after year.
I guess you may have noticed that it is pink. Her favorite color. Imagine that if you will!! ;D
When my precious Granny passed away in her own bed, she had this pillowcase under her beautiful bald head. I brought it home with me after the funeral. I don't sleep on it - I just treasure it. It was hers and it is special to me. It is a pretty pink treasure.
