Something I have had for years

I have had this set for years and have never known what it is. The large bowl is seven and a half inches and the small bowls are five and a half inches. the whole thing stands only nine inches tall. All I can make out of the stamp is Landcaster & Sons , Hanley England. I would love to know what it is and where it came from. I got it from a Great Aunt years ago but she is gone now .
