This plate would have been a sample for the Ararat Shrine Temple - location unknown. 6010 (as shown on the backstamp) denoted the Portland pattern (Underglaze Print Pattern: 6010), and 14 would have been the color of blue used.

The Shrine of North America is a philanthropic fraternity that grew out of Freemasonary over a century ago. See the photo at the bottom of the page of Pres. Harry Truman wearing his Ararat Shrine Temple fez.
