Can anyone tell me about this?

This was given to me 40 years ago by an old friend who at the time was 70 years old and said that it belonged to her mother. I'm not sure how far back the history goes, but I would love to know more about what I have. There are no identifying marks that I can see. If anyone has ANY information I would appreciate it! Inside it has 3 shelves with slots and a pull out top for writing.
