Three vintage Stangl Pottery dinner plates, one is Colonial Tangerine and two are Colonial Green or Silver Green.  Distinctive fluted or ribbed petal ware design, produced between 1926-1940.  Each plate has a diameter of 10”  
They are all in excellent vintage condition showing no cracks, no chips, no crazing.  
There are “blemishes” from when they were made as shown in photos.
Please review all the photos carefully they provide the best description and details. 
Thank you for looking
