Mid-century vintage Iroquois restaurant china bowls, heavy white ironstone with floral design in red. This is a set of six bowls.
I believe these are cereal / oatmeal bowls, but they'd be nice for a smallish bowl of soup at lunch or supper, too. They're about 5 1/4" in diameter across the bowl rim.
All have been used, and do show wear / utensil marks. No chips, these are very sturdy and made to last!
