Just got this on another forum but they aren't allowed to tell value. Anyone wanna guess?
Your plate is indeed decorated with the Two Temples II Reversed pattern. It is an example of an underglaze rubber stamp pattern by Southern Potteries, Inc., Erwin, Tennessee, c. 1917-1957. In the 1930's the name "Blue Ridge" was adopted. The shape is Trellis Shape -- a molded border pattern under a wash of blue. The factory name was seldom marked on the back of the ware; however, the retailer's name is often found. This information is documented on page 154 of "Blue Ridge Dinnerware, Revised 3rd edition" by Newbound. I also devote several pages in my self-published work: "Willow Ware Made in the U.S.A. An Identification Guide."
