1950s? STATE PLATE- KENTUCKY - GREEN RIM/GOLD

THIS IS AN OLDER COLLECTOR'S PLATE COMMEMORATING THE STATE OF "KENTUCKY".  THE FRONT DEPICTS THE STATE OF KENTUCKY AND SEVERAL SCENES, INCLUDING: CARDINAL BIRD, MY OLD KENTUCKY HOME, CHURCHILL DOWNS, KENTUCKY LAKE, AND ABRAHAM LINCOLN BIRTHPLACE.  THE REVERSE HAS A STAMP THAT READS: SHAW SUPPLY COMPANY NASHVILLE, TENN.   AND ANOTHER STAMP THAT READS: HL (the makers mark for Homer Laughlin) NAUTILUS MADE IN U.S.A. B54 N5.   IT APPEARS TO BE FROM THE 1950s, BUT I AM NOT SURE.  IT IS IN GREAT CONDITION -- NOT CRACKED OR CHIPPED.
