This design has been identified as Pittsburgh Country Club, thanks to a bit of ephemera discovered this this topmark. The club, founded in 1893, was purchased in 1936 and is now part of Frick Park in Pittsburgh.

This plate was made by Mayer China and is 9 5/8" in diameter. With its curlicues on the border that are frequently associated with 1920s designs and given the year the club was sold, it would probably have been made in the 20s-early 30s.

It is in excellent condition with medium utensil and stacking marks but no chips or cracks. (The photo of the Pittsburgh Country Club book is not included in this sale.)
