Norman Rockwell plate Summer Respite by Gorham

Summer Respite" is the first issue in American Landscapes series. Issued by Gorham China in a limited edition in 1980. The plate image is based on the Four Seasons Series of 1959. A boy sits on a fence and watches a train go by in the distance. It's 10 1/2" wide and in excellent condition with no flaws. No certificates were ever issued for these plates. I do not have the original box.
