Currier & Ives Blue by Royal made in USA.  This is the tab handled cake plate that measures 11 1/2" x 10 1/2".  This plate DOES NOT have crazing but it does have a brown spot the size of a dime just under the horse that is on the cliff.  Very small and almost undetectable.  There is a small flat chip under the left handle.  They were produced 1950-1970.  This cake plate is called "Rocky Mountain" and is in very good pre-owned condition for that era.
