All I know is they have been in the family for at least 50 years
Been in the family at least 50 years, they were my grandmothers and my grandfather got them for her from a house he was renovating. We don't really know how old they are or what they may be worth, but will add some pictures here for you to help me out. Thank you.

Nothing traditional Chinese. Closeup shots would be needed to verify if this is printed, Japanese or other. Is there some sort of marking on the bottom of one of them?
Yes here is a close up
The closeups confirm that the lines are printed and, the decoration style is not Asian at all.
