Vintage Platinum Blue heavy ironstone china restaurantware dinner plates, Lamberton - Scammell pottery, made in Trenton New Jersey, mid 20th century.
The color is a pale ice blue - I have white eggs on the top so you can get a true feel for the color here, these are so pretty!
It's a set of SEVEN plates 9 3/4" in diameter, all showing finish wear and scratching from use. No chips or cracks to any of these.
