Mid-Century Table Lamp

This table lamp belonged to my Mother. I have a matched pair. I know she purchased them after June of 1957 , but before 1961. My parents lived in Lake Charles, Louisiana , but shopped frequently in Houston. The lamps are robin egg blue and has a gold crackle on the "crown" area. I can not find a maker or mark of any kind. I would love to know more about these lamps. They are in working order and are in great condition.
